Wave-energized diode pump

ABSTRACT

Disclosed is an apparatus that floats at the surface of a body of water over which waves pass. Passing waves cause a nominally vertical axis of the apparatus to tilt away from an axis normal to the resting surface of the body of water. Tilting of sufficient magnitude and duration allows a fluid to flow through a channel that in an un-tilted apparatus would require the gravitational potential energy of the fluid to increase (i.e., to flow uphill), but, because of the tilt allows the fluid to flow through the channel in a downhill direction. Flowing water is trapped at a plurality of levels which in an un-tilted apparatus are higher than the respective levels from which the fluid has flowed. A subsequent tilt of the apparatus in a sufficiently different direction, and of a sufficient magnitude and duration, causes the trapped water to flow to new, yet higher levels. Successive wave-driven tilts of the apparatus incrementally raise water to a height and/or head from which a portion of its gravitational potential energy can be released, and/or converted to electrical power, by causing the water to return to a lower level by flowing through a water turbine thereby energizing an operationally connected generator, or through some other apparatus that performs a useful function when supplied with a flow of high-pressure water.

BACKGROUND

Extracting energy from ocean waves has proven to be a difficult endeavor. Complex devices are expensive and tend to be fragile. And devices with articulating elements are prone to damage during storms. In fact, devices with moving parts tend to require frequent maintenance and repair and therefore produce power that tends to be prohibitively expensive.

What has been needed is a wave-energy conversion technology, apparatus, and/or technology that is simple, has a minimum number of moving parts, and has no articulating elements. What has been needed is a wave-energy conversion technology, apparatus, and/or technology that requires little, if any, maintenance or repair over a reasonable (e.g. 30-year) lifetime and produces electrical power at a cost lower than that produced through the burning of fossil fuels.

SUMMARY OF THE INVENTION

Disclosed is a mechanism, apparatus, system, and method which permits rich, and currently under-utilized, natural and renewable marine energy resources to be efficiently harvested and put to good purpose, offsetting and potentially supplanting a portion of the electrical power generated on land and/or through the burning of fossil fuels. The foregoing is achieved by an object floating at the surface of the ocean that will tend to be moved by passing waves. Floating objects may rise and fall. They may move back and forth. However, they also tend to tilt about a vertical axis (i.e. to pitch and/or roll).

When tilted, a first position on a floating object that would (in the absence of waves and the resulting tilting of the object) be below a second position on the object, may, during at least a portion of the tilt, e.g., the most angularly extreme portion, and/or the portion of greatest tilt, be above the second position. Thus, whereas a fluid might not flow from the first position to the second position in a resting object, i.e. an object free from waves and tilt, during a tilt of sufficient angularity and duration fluid would indeed flow from the first to the second position. And, when such a tilt has ended, perhaps through a manifestation of a new tilt in a different direction, a fluid that flowed from the first to the second position would find itself higher and with greater gravitational potential energy than before it flowed from the first to the second position.

By repeating such a pattern of nominally “uphill” flows, e.g. from one side of the object to another side, the height of a fluid might be raised to a substantial degree, e.g., by 50 meters, above the mean level of the resting body of water, and the resulting significant increase in the gravitational potential energy of that fluid might then be converted into electrical power by passing that fluid through a water turbine. Alternately, its increased head pressure might be used to desalinate water or facilitate the extraction of minerals (or other chemicals or compounds) from seawater, e.g. by passing the water through an adsorbent substance or a membrane.

Disclosed is an apparatus that utilizes the tilting motion imparted to it by passing waves to incrementally raise water (or another liquid) above the level of the resting surface of the body of water on which the apparatus floats. The disclosed tilt-induced raising of water may be accomplished by and/or with a variety of embodiments, designs, architectures, and/or components.

The scope of the present invention includes, but is not limited to, embodiments in which water tends to flow in a radial pattern that when projected onto a horizontal plane of each embodiment (e.g. normal to a vertical longitudinal axis of each embodiment), tends to travel from a position near an outer perimeter of the embodiment toward and/or to a position near the center of the embodiment, and then from a position near the center of the embodiment to a position near an outer perimeter of the embodiment. The scope of the present invention includes, but is not limited to, embodiments in which water tends to flow in a circumferential pattern that when projected onto a horizontal plane of each embodiment (e.g. normal to a vertical longitudinal axis of each embodiment), tends to travel in circular paths approximately concentric with the center of the embodiment and/or a vertical longitudinal axis thereof.

In other words, the scope of the present invention includes embodiments in which water flows by any horizontal distance, any vertical distance, and any total distance, during any single tilt of the embodiments.

The scope of the present invention includes embodiments in which fluid flows through a channel incorporating any type of valve, and type of anti-suction aperture, valve, or mechanism.

The scope of the present invention includes, but is not limited to, embodiments in which any angle of tilt, i.e., tilt of any zenith angle, within any vertical plane, must be reached or exceeded before water flows between at least one pair of water-holding enclosures. The scope of the present invention includes, but is not limited to, embodiments in which the angle of tilt, within any vertical plane, that must be reached or exceeded before water flows between at least one pair of water-holding enclosures is 3 degrees, 5 degrees, 7 degrees, 10 degrees, 15 degrees, 20 degrees, and 30 degrees.

The scope of the present invention includes, but is not limited to, embodiments in which the azimuthal angle of tilt, i.e., relative to an orientation of the embodiment, determines which subset of an embodiment's plurality of water-flow channels are characterized by active flows of water, and which are characterized by no flow. The scope of the present invention includes, but is not limited to, embodiments in which the repeated tilting of the embodiments at a variety of azimuthal angles of tilt, e.g., at approximately opposite azimuthal angles of tilt, results in a series of azimuthal-angle-of-tilt-specific water flows that act in series to raise a fluid from a lower elevation to a higher elevation.

With respect to any particular embodiment, the amount of tilt that must be reached or exceeded before water flows between at least one pair of water-holding enclosures tends to be correlated with the incremental vertical distance that must be travelled in order for water to move from one enclosure to another (e.g., the average height of the enclosures and/or their relative vertical offsets between levels).

With respect to any particular embodiment, the amount of tilt that must be reached or exceeded before water flows between at least one pair of water-holding enclosures tends to be inversely correlated with the horizontal distance that must be travelled in order for water to move from one enclosure to another (e.g. the average length of the pipes or ramps through which water flows between enclosures).

The scope of the present invention includes, but is not limited to, embodiments in which a fluid flow through a relatively long channel leading from a relatively lower elevation and/or height within the embodiment to a relatively higher elevation and/or height within the embodiment is achieved through a series of consecutive constituent fluid flows through relatively short channels—each relatively short channel leading from an preceding intermediate fluid repository to a succeeding fluid repository.

Fluid flow from lower-level intermediate fluid repository to a succeeding fluid repository is all or nothing, i.e., if the fluid fails to flow into the succeeding fluid repository then it will tend to flow back into the lower-level intermediate fluid repository. Fluid within an intermediate fluid repository will tend to remain trapped within that intermediate fluid repository unless and until the embodiment of which it is a part experiences and/or is subjected to a “sufficient and/or favorable tilt,” i.e., a tile characterized by a specific and sufficient azimuthal angle (with respect to the embodiment), a sufficient zenithal angle (with respect to the embodiment's nominal vertical orientation), and a sufficient duration (providing enough time for fluid to flow from a particular intermediate fluid repository to a succeeding fluid repository).

An otherwise favorable tilt of insufficient duration may see a fluid flow out of an intermediate fluid repository, toward a succeeding intermediate fluid repository, only to stop flowing prior to entering the succeeding intermediate fluid repository, and then flowing back into the intermediate fluid repository from which it originated, e.g., when the zenithal angle of tilt falls below the minimum zenithal angle of tilt required for flow before the incremental flow has been completed.

However, with respect to a flow channel fluidly connecting preceding and succeeding intermediate fluid repositories, the combination of the flow channel and either of its adjacent fluidly connected fluid repositories may be likened to a fluid diode in the sense that in response to a favorable tilt gravity will draw the fluid in one intermediate fluid repository through a connecting fluid channel and deposit it in a succeeding intermediate fluid repository. However, in response to unfavorable tilts of the respective embodiment, fluid remains trapped within an intermediate fluid repository. Thus, an intermediate fluid repository, in conjunction with an inter-repository fluid channel is analogous to, and/or constitutes, a fluid diode in which a fluid flows primarily if not entirely in a single direction within the larger, complete, and/or composite, fluid channel of which it is a part.

A particular constituent fluid diode, within an embodiment's complete, comprehensive, and/or composite, fluid channel will typically permit, facilitate, and/or manifest, a gravitationally-induced fluid flow in response to tilts of the embodiment occurring within a relatively narrow range of azimuthal angles, i.e., the fluid diode's active, responsive, and/or enabled, azimuthal angles. However, by adapting and/or configuring an embodiment's composite fluid channel such that the individual composite fluid diodes of which it is comprised have overlapping, complementary, and/or different active azimuthal angles, the azimuthal tilt angles to which an embodiment might be expected to experience, e.g., when mounted on a platform or buoy floating adjacent to an upper surface of a body of water over which waves pass, will tend to result in an incremental but steady flow of fluid from the inlet of the embodiment's fluid channel to its outlet.

The reason that an individual fluid diode of the present disclosure manifests fluid flow (in the preferred direction of flow, from lower to higher elevations) is because the fluid diode incorporates, utilizes, and/or includes, an inclined fluid channel, an elevating fluid conduit, an inclined fluid ramp, etc., that connects a preceding intermediate fluid repository and a succeeding intermediate fluid repository. And, an angularly favorable tilt is one whose azimuthal angle, and zenithal angle, are sufficient to change a nominally inclined fluid channel (i.e., inclined with respect to an embodiment-specific frame of reference) connecting a serially adjacent pair of intermediate fluid repositories into a fluid channel that is, because of the azimuthal and zenithal angles of the tilt, effectively, and/or with respect to gravity, a descending and/or downhill fluid channel through which gravity draws fluids to flow from the preceding to the succeeding intermediate fluid repositories. And, if such an angularly favorable tilt lasts long enough, the fluid contents of a preceding intermediate fluid repository may be entirely transferred by a gravitationally-induced flow through a connecting fluid channel to a succeeding intermediate fluid repository.

In the description of the present disclosure, the fluid channels fluidly connecting serially adjacent, and/or sequential, intermediate fluid repositories, may be referred to as a variety of terms, including, but not limited to: inclined channel, elevator conduit, elevator ramp, and ascending channel, or any variation thereof. In the description of the present disclosure, the intermediate fluid repositories which hold, trap, and/or capture, fluid between favorable tilts, may be referred to as a variety of terms, including, but not limited to: fluid repositories, and catchment basins. In the description of the present disclosure, the points, planes, apertures, and/or seams, at which inclined channels are fluidly connected to respective (i.e., preceding or succeeding) intermediate fluid repositories, and/or at which fluid diodes are interconnected, utilize terminology that is relative to the context of the reference, e.g., a fluid channel carrying fluid to an intermediate fluid repository may be referred to as an inlet channel, an inlet aperture, a source conduit, etc.; and, a fluid channel carrying fluid from an intermediate fluid repository may be referred to as an outlet channel, an outlet aperture, a receiving conduit, etc. Therefore, depending upon the context of a discussion and/or description, a particular fluid channel might be referred to as both an inlet channel and an outlet channel. Similarly, depending upon the context of a discussion and/or description, a particular intermediate fluid repository might be referred to as both a source fluid repository and a receiving fluid repository. Similarly, planes through which fluid flows within and/or between intermediate fluid repositories, fluid channels, and/or fluid diodes, might be referred to as apertures, e.g., inlet apertures and outlet apertures (depending upon the context of a discussion and/or description).

An embodiment's fluid channel is intended to raise fluid from a relatively lower height to a relatively greater height in response to tilting of the embodiment in response to external, e.g., environmental, buffeting of the embodiment. Therefore, the individual fluid diodes of which an embodiment's fluid channel is comprised tend to be oriented such that at least a range of approximately opposite azimuthal tilt angles will tend to move fluid from one intermediate fluid repository to another in response to a tilt of a first azimuthal angle, and then move it from that receiving intermediate fluid repository to another in response to a tilt of a second azimuthal angle, where the first and second azimuthal angles are approximately opposite, and/or different by approximately 180 degrees.

An embodiment of the present disclosure tends to elevate fluid through its serially and fluidly connected fluid diodic channels in response to tilting characterized by favorable azimuthal angles that differ by approximately 180 degrees. Another embodiment of the present disclosure tends to elevate fluid through its serially and fluidly connected fluid diodic channels in response to tilting characterized by favorable azimuthal angles that differ by approximately 120 degrees. Other embodiments of the present disclosure tend to elevate fluid through their respective serially and fluidly connected fluid diodic channels in response to tilting characterized by favorable azimuthal angles that differ by angles, including, but not limited to: 90 degrees, 60 degrees, 45 degrees, 30 degrees, 20 degrees, and 15 degrees. An embodiment of the present disclosure tends to elevate fluid through its serially and fluidly connected fluid diodic channels in response to tilting characterized by favorable azimuthal angles of any degree, and/or tilting characterized by any azimuthal angle.

An embodiment of the present disclosure utilizes intermediate inclined channels to fluidly connect intermediate fluid repositories such that a source of tilting action at the embodiment (e.g., wave action) will periodically, incrementally, sequentially, and/or approximately continuously, cause its constituent intermediate inclined channels to become reoriented with respect to gravity such that gravity causes fluid to flow from an intermediate fluid repository of a first elevation and/or height (relative to the embodiment) to another intermediate fluid repository of a second elevation and/or height (relative to the embodiment), wherein the second elevation is greater than the first. In this way, the embodiment incrementally, sequentially, step-wise, and/or impulsively, elevates fluid within its fluid channel from a relatively lower elevation to a relatively higher elevation, thereby imparting to the fluid gravitational potential energy and/or head pressure that may be used to energize a fluid turbine and/or for some other useful purpose.

Because a particular fluidic diode of the present disclosure manifests fluid flow within its respective nominally-inclined fluid channel in response to a tilt of a particular azimuthal direction, and only while that tilt is also of at least a threshold zenithal angle, a fluidic diode of the present disclosure behaves in a periodic manner, akin to a gated or digital circuit. And, because tilting of an embodiment will, depending upon its configuration and the environment in which it operates, tend to be cyclic with the tilting in one azimuthal direction being following by an approximate return to a vertical orientation prior to again being tilted in a different azimuthal (e.g., in an approximately opposite) direction, the environmental and/or ambient source tending to tilt an embodiment of the present disclosure, the ambient source of an embodiment's tilting tends to act as a clocking and/or gating signal to the embodiment. From this perspective, an embodiment of the present disclosure might be seen as analogous to a digital circuit that moves data from an input register, to another register, and to another, and to another, and so on . . . until that data is presented at an output register—where embodiments of the present disclosure move fluid instead of data, and the clock signals and energy which gate and drive the movements are provided by the external source of the embodiment's tilting.

With respect to an embodiment of the present disclosure that is mounted to, and/or incorporates, a buoyant structure, waves acting at the embodiment and causing it to tilt, e.g., in one azimuthal direction of tilt when approaching a wave crest, and in an approximately opposite azimuthal direction of tilt when approaching a wave trough, provide the embodiment's fluid channel, and the fluid diodes of which it is comprised, with a gating, timing, and/or clocking signal which regulates the flow of fluid through the embodiment's fluid diodes. Those wave-induced tilts of the embodiment then periodically allow gravity, and a tilt-induced gravitational potential energy with respect to individual fluid diodes, to move fluid within the embodiment's fluid channel from one or more fluid diodes to respective succeeding fluid diodes. The fluid diodes of which the embodiment's fluid channel is comprised allow fluid to move higher within the embodiment, and with respect to the embodiment's frame of reference, when the embodiment experiences tilts favorable to each respective fluid diode. Those fluid diodes prevent the water within them from flowing backward within the embodiment's fluid channel when the embodiment's tilt is not favorable to its forward flow. Thus, in response to tilting of an embodiment, fluid flows incrementally from fluid diode to fluid diode in a pattern that eventually elevates fluid to an elevated outlet from which its wave-derived gravitational potential energy may be efficiently harvested.

Because of their dependence upon gravity to cause fluid to flow within and/or through them, the fluid diodes of which an embodiment of the present disclosure may be comprised may be referred to as gravitational fluidic diodes. And, the fluid channel of an embodiment might be described as a fluidly connected concatenation of gravitational fluidic diodes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 shows a perspective side view of a power takeoff (PTO) representative of an embodiment of the present disclosure, provided mainly for illustration of concepts. The full embodiment of which the illustrated PTO is a part can include a flotation platform (not shown) to which the illustrated PTO is attached and the embodiment floats adjacent to an upper surface of a body of water over which waves pass. The illustration in FIG. 1 includes a rectangular plane 100 (i.e. a “deck”) beneath the PTO that is nominally parallel to the resting surface of the body of water on which the embodiment of which the PTO is a part floats, and is provided to assist the reader in evaluating the relative heights of the water-holding chambers on the left and right sides of the PTO.

A water-holding chamber (i.e. “chamber”) 101 is fluidly connected to a plurality of inlet pipes and/or apertures 102 through which water may enter the chamber 101. Chamber 101 is fluidly connected to chamber 103 by a pipe, tube, and/or conduit, 104. Pipe 104 originates at a lower portion and/or position on chamber 101 and connects to a relatively high portion and/or position of chamber 103. Thus, when the PTO is tilted by a sufficient degree within a vertical plane passing through chambers 101 and 103, water will tend to pass from chamber 101, through pipe 104, and into chamber 103. Furthermore, when such a tilt is completed and/or over, the water that has passed from chamber 101 to 103 will tend to be trapped within chamber 103 (since the input to pipe 104 with respect to chamber 103 is relatively high and will tend to remain above the upper surface of the water trapped within chamber 103).

A lower portion and/or position of chamber 103 is fluidly connected to an upper portion and/or position of chamber 105 by pipe 106. Thus, when the PTO is tilted by a sufficient magnitude and/or degree within a vertical plane passing through chambers 103 and 105, water will tend to pass from chamber 103, through pipe 106, and into chamber 105.

A tilt of sufficient degree that tends to raise chamber 101 and lower chamber 103 will tend to result in water flowing through pipe 104 from chamber 101 to chamber 103. And, an opposing tilt (i.e. a tilt in the opposite direction) of sufficient degree that tends to raise chamber 103 and lower chamber 105 will tend to result in water flowing through pipe 106 from chamber 103 to chamber 105. Thus, relative to the illustration in FIG. 1, a first counter-clockwise tilt will tend to move water from chamber 101 to chamber 103, thereby moving the water from a relatively lower chamber to a relatively higher chamber and leaving it trapped there. And, a second clockwise tilt will tend to move water from chamber 103 to chamber 105, thereby again moving the water from a relatively lower chamber to a relatively higher chamber and leaving it trapped there. Through a single cycle of tilting within a vertical plane passing through the opposing chambers 101/105 and 103, water that originated in chamber 101 is raised by a full chamber height (i.e., the height of chamber 101) and remains trapped there.

In response to a counter-clockwise tilt of sufficient magnitude, water trapped within chamber 105 will tend to flow into chamber 107 through pipe 108. And, in response to a clockwise tilt of sufficient magnitude, water trapped within chamber 107 will tend to flow into chamber 109 through pipe 110.

A series of sufficiently great tilting motions of alternating directions (e.g., clockwise and counter-clockwise) of the illustrated PTO will tend to take water introduced to the interior of chamber 101 through input pipes 102 and incrementally raise the height of that water through successive passages from chamber 101 to chambers 103, 105, 107, and 109. Water deposited into chamber 109 then flows out of that chamber through pipe 111 and through water turbine 112, which tends to rotate the operationally connected rotor of generator 113, thereby producing electrical power.

The PTO illustrated in FIG. 1 uses a wave-driven tilting of its respective embodiment to raise water from a relatively lower level and/or height, to a relatively higher level and/or height. It then converts the increased gravitational potential, and/or head pressure, of that raised water to cause a water turbine to rotate and to thereby generate electrical power.

FIG. 2 shows a side view of the same power takeoff (PTO) illustrated in FIG. 1. In FIG. 2, the PTO is configured in a horizontal orientation. In this orientation, water trapped in any particular water-holding chamber 101, 103, 105, 107, and/or 109, of the PTO would tend to remain within that chamber. In this orientation, water will not tend to flow through any of the pipes 104, 106, 108, and/or 110, because to do so the water would have to flow to height higher than the level of water within the chamber from which it would originate.

When the PTO is tilted in a clockwise direction to a sufficient degree, water from the body of water 113 on which the PTO's associated embodiment (not shown) floats will tend to flow 114 into the inlet pipes 102, after which successive tilts within a vertical plane passing through the opposing stacks of chambers, i.e. stack 103/107 and stack 101/105, 109, and of sufficient magnitude will (if the requisite degree of tilting is maintained for a sufficient period time) tend to flow into successively higher chambers, i.e., from 101 to 103 to 105 to 107 and to 109. Water deposited into uppermost chamber 109 is then able to flow out of the chamber through pipe 111 and thereafter through water turbine 112 and thereafter out of the PTO through pipe 115. Water flowing out of the mouth at the lower end of pipe 115 will return to the body of water 113 on which the PTO's associated embodiment (not shown) floats.

FIG. 3 shows a side sectional view of the same power takeoff (PTO) illustrated in FIGS. 1 and 2. For the purpose of illustration, the chamber walls nearest the reader in FIGS. 3-8 have been removed to permit the presence, volumes, and upper surfaces, of water (if any) contained within each chamber to be visible. FIGS. 3 to 8 are sectional views in which the section plane is immediately inside the chamber walls parallel to the illustration page and nearest the reader.

In FIG. 3, the PTO is configured in a tilted and/or rotated orientation. In FIGS. 1 and 2, a vector normal to the PTO's deck was oriented vertically as shown by line 116. The PTO configuration illustrated in FIG. 3 has resulted from a clockwise rotation of the PTO within the plane of the illustration that has rotated 117 the deck normal vector from the neutral orientation 116 of a horizontal PTO to a new orientation of 118.

The clockwise rotated configuration of the PTO has placed the inlet pipes 102 below the surface 113 of the body of water on which the PTO's associated embodiment (not shown) floats. As a consequence of the submergence of the inlet pipes 102, water flows 114 into chamber 101 and a volume of water 119 is momentarily trapped within that chamber. A portion 120 of the trapped water 119 extends into pipe 104 but is unable to flow uphill through pipe 104.

FIG. 4 shows a side view of the same power takeoff (PTO) illustrated in FIGS. 1-3. In FIG. 4, the PTO is configured in a tilted and/or rotated orientation that is counter to the rotation characterizing the orientation illustrated in FIG. 3. In FIGS. 1 and 2, a vector normal to the PTO's deck was oriented vertically as shown by line 116. The PTO configuration illustrated in FIG. 4 has resulted from a counter-clockwise rotation of the PTO within the plane of the illustration that has rotated 121 the deck normal vector from the orientation 118 characteristic of the PTO orientation illustrated in FIG. 3, and from the neutral orientation 116 of a horizontal PTO to a new orientation of 122.

The counter-clockwise rotated configuration of the PTO has raised the inlet pipes 102 above the surface thereby preventing any further inflow of water into chamber 101. Furthermore, the rotation has changed the angular orientation of pipe 104 such that water that was trapped within chamber 101 is now free to flow 123 “downhill” and to thereafter flow 124 into chamber 103 through the aperture 125 that fluidly connects the chamber 103 to pipe 104. The water that flows 124 into chamber 103 becomes trapped as a pool 126 at the bottom of that chamber. A portion 127 of the trapped water 126 extends into pipe 106 but is unable to flow uphill through pipe 106.

As a consequence of the water 119 that flows out of chamber 101, and flows 123 through pipe 104, and into 124 chamber 103, the level of the water within chamber 101 is reduced 128.

FIG. 5 shows a side view of the same power takeoff (PTO) illustrated in FIGS. 1-4. In FIG. 5, the PTO is configured in a tilted and/or rotated orientation that is counter to the rotations characterizing the orientations illustrated in FIG. 4, and similar to the rotation characterizing the orientation illustrated in FIG. 3. As was the case with the orientation illustrated in FIG. 3, water from body of water 113 on which the PTO's associated embodiment (not shown) flows 114 into water-holding chamber 101 and accumulates 119 therein.

The water 126 that accumulated within chamber 103 as a result of the counter-clockwise rotation illustrated in FIG. 4, now tends to flow 129 from chamber 103 to chamber 105 through pipe 106, thereby lowering 130 the level of the water 126 within chamber 103. Water flowing 131 into chamber 105 through aperture 132 tends to become trapped forming a pool 133 of water within the chamber.

FIG. 6 shows a side view of the same power takeoff (PTO) illustrated in FIGS. 1-5. In FIG. 6, the PTO is configured in a tilted and/or rotated orientation that is counter to the rotation characterizing the orientation illustrated in FIGS. 3 and 5. The PTO configuration illustrated in FIG. 6 has resulted from a counter-clockwise rotation of the PTO within the plane of the illustration that has rotated 121 the deck normal vector from the orientation 118 characteristic of the PTO orientation illustrated in FIGS. 3 and 5, and from the neutral orientation 116 of a horizontal PTO to the same orientation of 122 that characterizes the orientation illustrated in FIG. 4.

The counter-clockwise rotated configuration of the PTO has changed the angular orientation of pipe 104 such that water that was trapped within chamber 101 is now free to flow 123 “downhill” and to thereafter flow 124 into chamber 103. The water that flows 124 into chamber 103 becomes trapped as a pool 126 at the bottom of that chamber. Similarly, water that was trapped within chamber 105 as a result of the rotation of FIG. 5 is now free to flow 134 “downhill” and to thereafter flow 135 into chamber 103 through the aperture 136 that fluidly connects the chamber 107 to pipe 108. The water that flows 135 into chamber 107 becomes trapped as a pool 137 at the bottom of that chamber. A portion 138 of the trapped water 137 extends into pipe 108 but is unable to flow uphill through pipe 110.

As a consequence of the water 133 that flows out of chamber 105, and flows 134 through pipe 108, and into 135 chamber 107, the level of the water within chamber 105 is reduced 139.

FIG. 7 shows a side view of the same power takeoff (PTO) illustrated in FIGS. 1-6. In FIG. 7, the PTO is configured in a tilted and/or rotated orientation that is counter to the rotations characterizing the orientations illustrated in FIGS. 4 and 6, and similar to the rotation characterizing the orientation illustrated in FIGS. 3 and 5. As was the case with the orientations illustrated in FIGS. 3 and 5, water from body of water 113 on which the PTO's associated embodiment (not shown) flows 114 into water-holding chamber 101 and accumulates 119 therein.

The water 126 that accumulated within chamber 103 as a result of the counter-clockwise rotations illustrated in FIGS. 4 and 6, now tends to flow 129 from chamber 103 to chamber 105 through pipe 106, thereby lowering 130 the level of the water 126 within chamber 103. Water flowing 131 into chamber 105 tends to become trapped forming a pool 133 of water within the chamber. Likewise, the water 137 that accumulated within chamber 107 as a result of the counter-clockwise rotations illustrated in FIG. 4, now tends to flow 140 from chamber 107 to chamber 109 through pipe 110, thereby lowering 141 the level of the water 137 within chamber 107. Water flowing 142 into chamber 109 tends to become trapped forming a pool 143 of water within the chamber.

Water 143 within chamber 109 tends to flow out of the chamber through pipe 111 and therethrough water turbine 112, after which it flows 144 through and out of pipe 115 thereby returning to the body of water 113 from which it originated.

FIG. 8 shows a side view of the same power takeoff (PTO) illustrated in FIGS. 1-7. In FIG. 8, the PTO is configured in a tilted and/or rotated orientation that is counter to the rotation characterizing the orientation illustrated in FIGS. 3, 5 and 7. The PTO configuration illustrated in FIG. 8 has resulted from a counter-clockwise rotation of the PTO within the plane of the illustration that has rotated 121 the deck normal vector from the orientation 118 characteristic of the PTO orientations illustrated in FIGS. 3, 5 and 7, and from the neutral orientation 116 of a horizontal PTO to the same orientation of 122 that characterizes the orientation illustrated in FIGS. 4 and 6.

The counter-clockwise rotated configuration of the PTO has changed the angular orientation of pipes 104 and 108 such that water that was trapped within respective chambers 101 and 105 is now free to flow 123 and 134 “downhill” and to thereafter flow 124 and 135 into respective chambers 103 and 107 where it is trapped in pools 126 and 137.

As a consequence of the water 119 and 133 that flows out of chambers 101 and 105, the level of the water within chambers 103 and 105 are reduced 128 and 139.

Because the water deposited in chamber 109 flows out through pipe 111 and energizes water turbine 112, the level of the water within chamber 109 is reduced 145.

Through a wave-driven repeated and/or oscillatory tilting and/or rotation of the PTO, and its associated embodiment (not shown), the orientations illustrated in FIGS. 7 and 8 may be repeated many times, and the result of that oscillatory tilting is the continuous transfer of water from one stack of chambers (e.g., 101/105/109) to the other stack of chambers (e.g., 103/107) and back again. When tilted within a vertical plane passing through the chambers 101, 103, 105, 107, and 109 (or tilted such that a component of the tilting is within such a vertical plane) to a sufficient degree and for a sufficiently long period of time (i.e., long enough for water to flow from one chamber to another), the PTO illustrated in FIGS. 1-8 will incrementally, serially, and ongoingly, raise water from the body of water 113 on which the embodiment floats up to chamber 109 where its resulting gravitational potential energy and/or head pressure pushes it through water turbine 112 thereby imparting rotational energy to the rotor of operationally connected generator (113 in FIG. 1).

The PTO illustrated in FIGS. 1-8 converts a portion of the energy of ocean waves into gravitational potential energy, and thereafter uses a portion of that potential energy to do useful work, such as to generate electrical power. Another embodiment uses the gravitational potential energy of the water deposited in chamber 109 to desalinate water. And another embodiment uses that potential energy to extract minerals from seawater (e.g. by pushing the water through an adsorbent substance, filter, or membrane). The scope of the present invention includes embodiments that utilize the gravitational potential energy of the raised water to do any and every kind of useful work.

The scope of the present invention includes any number, shape, size, and/or volume of water-holding chambers. The scope of the present invention includes any arrangement: horizontal, vertical, and/or spatial, of water-holding chambers, including, but not limited to, the distances between chambers, vertically, horizontally, and/or spatially. The scope of the present invention includes any number, shape, cross-sectional area, diameter, size, length, and/or volume of inter-chamber pipes, within the PTO and/or fluidly connecting any two chambers. The scope of the present invention includes any means, mechanism, device, and/or component, by which the flow of water through the inter-chamber pipes is directed, regulated, adjusted, and/or modified, including, but not limited to, any and every means, mechanism, device, and/or component, by which water is compelled to flow in only a single direction, and/or only toward a respective receiving chamber. The scope of the present invention includes any means, mechanism, device, channel, conduit, pipe, aperture, and/or component, by which water is permitted to flow into an initial chamber (e.g., chamber 101 in FIG. 1), including inlet pipes and/or apertures that incorporate one-way valves to prevent water from flowing out of such an initial chamber after having flowed in. The scope of the present invention includes any means, mechanism, device, pipe, aperture, and/or component, by which raised water is directed into, and/or permitted to enter, a water turbine. The scope of the present invention includes any type, design, variety, size, and/or volume, of water turbine. The scope of the present invention includes any type, design, variety, size, and/or rated power, of generator and/or alternator, including permanent magnet generators, induction generators, and self-excited synchronous generators.

FIG. 9 shows a perspective side view of an embodiment of the present disclosure. The embodiment incorporates four 170-173 of the same power takeoffs (PTOs) illustrated in FIGS. 1-8. The embodiment incorporates a buoyant platform and partial enclosure 174 that floats adjacent to the surface 175 of a body of water over which waves pass. The embodiment's four 170-173 PTOs are attached to a deck 176 which was represented in FIGS. 1-8 as 100.

As illustrated and explained in FIGS. 1-8, each PTO includes a set of inflow pipes 177 which penetrate a side wall of the embodiment's buoy 174 and were denoted as 102 in FIGS. 1-8. And, as illustrated and explained in FIGS. 1-8, each PTO includes a pipe 178 (denoted as 111 in FIGS. 1-8) that directs water raised by the PTO into a water turbine 179 (denoted as 112 in FIGS. 1-8), which energizes an operably connected generator 180 (denoted as 113 in FIG. 1), and includes a pipe 181 that guides effluent from the water turbine 179 back to the body of water 175 on which the embodiment floats.

When the embodiment tilts 182, fully or partially, within a vertical plane passing through the water-holding chambers of PTOs 170 and/or 171, then a tilt in one direction (clockwise with respect to the embodiment orientation illustrated in FIG. 9) then water will tend to flow into the lowest chamber of PTO 171. And, when the embodiment tilts 182 in the opposite direction (counter-clockwise with respect to the embodiment orientation illustrated in FIG. 9) then water will tend to flow into the lowest chamber of PTO 170. And, water will tend to continuously run through and energize the water turbines of each PTO 170 and 171.

When the embodiment tilts 183, fully or partially, within a vertical plane passing through the water-holding chambers of PTOs 172 and/or 173, then a tilt in one direction (clockwise with respect to the embodiment orientation illustrated in FIG. 9) then water will tend to flow into the lowest chamber of PTO 172. And, when the embodiment tilts 183 in the opposite direction (counter-clockwise with respect to the embodiment orientation illustrated in FIG. 9) then water will tend to flow into the lowest chamber of PTO 173 (i.e. into input pipes 177). And, water will tend to continuously run through and energize the water turbines of each PTO 172 and 173.

Since most, if not all, directions of wave-induced tilting of the embodiment will tend to involve a component tilt in both of the embodiment's orthogonal vertical planes (passing through chambers of each of the four PTOs), i.e. in the planes exemplified by tilt arrows 182 and 183, most tilting of sufficient degree and/or magnitude, and of sufficient duration, will tend to cause all four PTOs to lift water and generate electrical power.

The buoyant platform 174 is square in horizontal cross-section and has a flat bottom.

The illustrated embodiment is similar to the embodiment illustrated in FIGS. 9-11. However, whereas the embodiment illustrated in FIGS. 9-11 raised water in response to tilting occurring with two orthogonal vertical planes, the embodiment illustrated in FIG. 12 raises water in response to tilting occurring with four vertical planes 204-207 each passing through a vertical longitudinal axis of the embodiment and in which each plane is offset from its neighboring planes by approximately 45 degrees.

The embodiment illustrated in FIG. 12 incorporates a buoyant platform 208 and partial enclosure that floats adjacent to the surface 209 of a body of water over which waves pass. Each of the embodiment's four PTOs 200-203 include a set of inlet pipes, e.g., 210, and a water turbine, e.g., 211.

The PTO 201, like each of the other PTOs, includes the same components, connections, and operational behaviors, as were described and explained in relation to FIGS. 1-8.

FIG. 14 shows a side sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 12 and 13 wherein the vertical section plane is specified in FIG. 13 and the section is taken across line 14-14.

The scope of the present invention includes any number, shape, size, and/or volume of water-holding chambers. The scope of the present invention includes any arrangement: horizontal, vertical, and/or spatial, of water-holding chambers, including, but not limited to, the distances between chambers, vertically, horizontally, and/or spatially.

FIG. 15 shows a perspective side view of a power takeoff (PTO) characteristic of an embodiment of the present disclosure. The PTO illustrated in FIG. 15 is identical to the PTO illustrated in FIGS. 1-8 except that whereas the PTO of FIGS. 1-8 communicated water from one water-holding chamber to another through pipes, the PTO of FIG. 15 communicates water from one water-holding chamber to another through “ramps”, funnels, and/or constricting channels.

The full embodiment of which the illustrated PTO is a part includes a flotation platform (not shown) to which the illustrated PTO is attached and the embodiment floats adjacent to an upper surface of a body of water over which waves pass. The illustration in FIG. 15 includes a rectangular plane 230 (i.e. a “deck”) beneath the PTO that is nominally parallel to the resting surface of the body of water on which the embodiment of which the PTO is a part floats, and is provided to assist the reader in evaluating the relative heights of the water-holding chambers on the left and right sides of the PTO.

A water-holding chamber (i.e. “chamber”) 231 is fluidly connected to a plurality of inlet pipes and/or apertures 232 through which water may enter the chamber 231. Chamber 231 is fluidly connected to chamber 232 by a ramp, funnel, and/or constricting channel 233 to another chamber 234. Chamber 234 is higher than chamber 231 relative to the deck 230. And water within chamber 231 would not tend to travel from that chamber to chamber 234 through ramp 233, if the embodiment to which the PTO was attached was at rest and in a nominal orientation at the surface of a body of water, since the water would be required to flow uphill in order to do so. However, when a wave or other disturbance causes the embodiment to which the PTO is attached to tilt in a favorable direction, and for an adequate duration, then the tilting of ramp 233 allows water to flow from chamber 231 to chamber 234 in a gravitationally favored downhill manner. When the tilt facilitating the flow of water from chamber 231 to chamber 234 ends, then water deposited within chamber 234 tends to be trapped therein.

Chamber 234 is fluidly connected to chamber 235 by ramp 236. During periods of favorable tilt, water will tend to flow through ramp 236 and thereafter to be deposited and/or trapped within chamber 235. Chamber 235 is fluidly connected to chamber 237 by ramp 238. During periods of favorable tilt, water will tend to flow through ramp 238 and thereafter to be deposited and/or trapped within chamber 237. Likewise, chamber 237 is fluidly connected to chamber 239 by ramp 240. During periods of favorable tilt, water will tend to flow through ramp 240 and thereafter to be deposited and/or trapped within chamber 239.

Water deposited and/or trapped within chamber 239 then flows out of the chamber through outflow pipe 241 and into and through water turbine 242 thereby rotating the water turbine and the operably connected generator 243 rotor, and thereby generating electrical power. After passing through the water turbine 242, the water flowing out of chamber 239 is released back to the environment around the embodiment through effluent pipe 244.

Through successive, serial, and/or periodic, tilting in an appropriate and/or favorable direction, and for a sufficient duration, the PTO illustrated in FIG. 15 will take water from the body of water on which its associated embodiment and/or buoyant platform floats and raise and/or elevate it through successive incremental steps and/or distances until it achieves a height, gravitational potential energy, and/or head pressure, defined by the height of chamber 239 above the body of water on which the embodiment floats, and/or above the water turbine 242. After lifting the water to a desirable height, gravitational potential energy, and/or head pressure, the PTO illustrated in FIG. 15 passes at least a portion of that water through a water turbine thereby causing a generator operably connected to the water turbine to generate electrical power. Other PTOs, incorporated within other embodiments, use the resulting height, gravitational potential energy, and/or head pressure, of the lifted water to perform other useful kinds of work, including, but not limited to: desalinating water, and extracting minerals from seawater.

FIG. 16 shows a top-down view of the same embodiment of the present disclosure that is illustrated in FIG. 15.

FIG. 17 shows a side sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 15 and 16 wherein the vertical section plane is specified in FIG. 16 and the section is taken across line 17-17.

When subjected to a tilt of appropriate direction (clockwise with respect to the PTO orientation illustrated in FIG. 17), magnitude, and duration, water may enter 245 the water-holding chamber 231 through inlet pipes 232. When subjected to a tilt of a contrary direction (counter-clockwise with respect to the PTO orientation illustrated in FIG. 17), magnitude, and duration, water may flow from chamber 231, through constricted channel, and/or over ramp, 233, and into chamber 234. Water exiting ramp 233 does so from the mouth 246 of a distal ramp end (distal with respect to chamber 231) from which the water falls 247 into the receiving chamber 234.

With respect to any degree of tilting, regardless of direction, that might reasonably be expected to be imparted to the PTO and its associated buoyant embodiment (not shown) by passing waves, the water that falls out of the distal end of the ramp 233 and into chamber 234 is thereafter unable to return to that ramp 233 and therethrough to chamber 231. Such water is, with respect to any normal operational mode or motion unable to flow back down to the lower chamber from which it originated.

When subjected to a tilt of appropriate direction (clockwise with respect to the PTO orientation illustrated in FIG. 17), magnitude, and duration, water held within chamber 234 may travel through ramp 236 and thereafter flow 248 out of the mouth 249 at the distal end of that ramp, thereby falling into, and being trapped within, chamber 235.

When subjected to a tilt of appropriate direction (counter-clockwise with respect to the PTO orientation illustrated in FIG. 17), magnitude, and duration, water held within chamber 235 may travel through ramp 238 and thereafter flow 250 out of the mouth 251 at the distal end of that ramp, thereby falling into, and being trapped within, chamber 237.

When subjected to a tilt of appropriate direction (clockwise with respect to the PTO orientation illustrated in FIG. 17), magnitude, and duration, water held within chamber 237 may travel through ramp 240 and thereafter flow 252 out of the mouth 253 at the distal end of that ramp, thereby falling into, and being trapped within, chamber 239.

Water deposited within chamber 239 flows out of the chamber through pipe 241 and therethrough into and/or through water turbine 242. Water flowing through water turbine 242 causes the operably connected generator 243 to generate electrical power. After flowing through water turbine 242, the water flows through and out of effluent pipe 244 from which it returns to the body of water from which it originated, perhaps to again enter chamber 231 through inlet pipes 232.

The scope of the present invention includes any number, shape, size, and/or volume of water-holding chambers. The scope of the present invention includes any arrangement: horizontal, vertical, and/or spatial, of water-holding chambers, including, but not limited to, the distances between chambers, vertically, horizontally, and/or spatially. The scope of the present invention includes any number, shape, cross-sectional area, diameter, size, length, and/or volume of inter-chamber pipes, within the PTO and/or fluidly connecting any two chambers. The scope of the present invention includes any means, mechanism, device, and/or component, by which the flow of water through the inter-chamber pipes is directed, regulated, adjusted, and/or modified, including, but not limited to, any and every means, mechanism, device, and/or component, by which water is compelled to flow in only a single direction, and/or only toward a respective receiving chamber. The scope of the present invention includes any means, mechanism, device, pipe, aperture, and/or component, by which water is permitted to flow into an initial chamber (e.g., chamber 231 in FIG. 17), including inlet pipes and/or apertures that incorporate one-way valves to prevent water from flowing out of such an initial chamber after having flowed in. The scope of the present invention includes any means, mechanism, device, pipe, aperture, and/or component, by which raised water is directed into, and/or permitted to enter, a water turbine. The scope of the present invention includes any type, design, variety, size, and/or volume, of water turbine. The scope of the present invention includes any type, design, variety, size, and/or rated power, of generator and/or alternator. The scope of the present invention includes any means, mechanism, device, system, module, and/or component, by which generated electrical power is stored.

FIG. 18 shows a side sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 15-17 wherein the vertical section plane is specified in FIG. 16 and the section is taken across line 18-18.

In response to appropriate directions, magnitudes, and durations of tilting of the PTO (and its associated buoyant embodiment, not shown):

Water that flows 254 and/or enters chamber 231 through inlet pipes 232 becomes trapped within that chamber due to the height of the inlet pipes 232 relative to the bottom of the chamber 231.

Water trapped within chamber 231 flows 257 “up” (which is “down” during periods of appropriate tilting) ramp 233 and thereafter flows 247 out of the mouth 246 at the distal end of the ramp 233, thereby becoming trapped within chamber 234 due to the height of the inlet ramp's 233 mouth 246 relative to the bottom of the chamber 234.

Water trapped within chamber 235 flows 258 “up” (which is “down” during periods of appropriate tilting) ramp 238 and thereafter flows 250 out of the mouth 251 at the distal end of the ramp 238, thereby becoming trapped within chamber 237 due to the height of the inlet ramp's 238 mouth 251 relative to the bottom of the chamber 237.

Water deposited and/or trapped (i.e. unable to flow backward) within chamber 239 flows 255 into and through pipe 241, thereafter flowing into and through water turbine 242, and thereafter flowing into, and through; and finally flowing 256 out of, effluent pipe 244.

FIG. 19 shows a side sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 15-18 wherein the vertical section plane is specified in FIG. 16 and the section is taken across line 19-19.

In response to appropriate directions, magnitudes, and durations of tilting of the PTO (and its associated buoyant embodiment, not shown):

Water that flows 254 and/or enters chamber 231 through inlet pipes 232 becomes trapped within that chamber due to the height of the inlet pipes 232 relative to the bottom of the chamber 231.

Water trapped within chamber 234 flows 259 “up” (which is “down” during periods of appropriate tilting) ramp 236 and thereafter flows 248 out of the mouth 249 at the distal end of the ramp 236, thereby becoming trapped within chamber 235 due to the height of the inlet ramp's 236 mouth 249 relative to the bottom of the chamber 235.

Water trapped within chamber 237 flows 260 “up” (which is “down” during periods of appropriate tilting) ramp 240 and thereafter flows 252 out of the mouth 253 at the distal end of the ramp 240, thereby becoming trapped within chamber 239 due to the height of the inlet ramp's 240 mouth 253 relative to the bottom of the chamber 239.

Water deposited and/or trapped (i.e. unable to flow backward) within chamber 239 flows 255 into and through pipe 241, thereafter flowing into and through water turbine 242, and thereafter flowing into, and through; and finally flowing 256 out of, effluent pipe 244.

Through successive tilts of a favorable magnitude and duration, and an alternating approximately contrary direction (e.g., alternating tilts of clockwise and counter-clockwise directions relative to the PTO orientation illustrated in FIGS. 15 and 17) water is incrementally raised to chambers of successively greater heights above the first chamber, and/or the surface of the body of water from which the raised water originates, until it reaches a height from which its increased height, gravitational potential energy, and/or head pressure, permits its passage through a water turbine to energize a generator operably connected to the water turbine, thereby indirectly converting the energy of the waves that tilt the PTO, and its associated embodiment (not shown), into a reservoir of water of increased gravitational potential energy, and thereafter into a rotational kinetic energy of a water turbine, and thereafter into electrical energy.

Because water raised to any particular chamber, height, and/or level, is unable to flow back into the chamber, and/or to the height or level from which it originated, the PTO extracts energy from wave-induced tilts when they are available and/or occur, and the potential energy of any partially raised water is preserved during any periods during which the wave climate is inadequate to achieve the angle, magnitude, and/or duration, of tilting required to further raise water.

FIG. 20 shows a perspective side view of a power takeoff (PTO) characteristic of an embodiment of the present disclosure. The full embodiment of which the illustrated PTO is a part includes a flotation platform (not shown) to which the illustrated PTO is attached and the embodiment floats adjacent to an upper surface of a body of water over which waves pass.

The illustrated PTO is similar to the PTO illustrated in FIGS. 1-8. However, whereas the inter-chamber pipes (104, 106, 108 and 110) of the PTO illustrated in FIGS. 1-8 were open, unthrottled, and without valves, each inter-chamber pipe 280-283 of the PTO illustrated in FIG. 20 includes a one-way valve 284-287, respectively, that permits water to flow in only a single direction (i.e. toward the respective receiving chamber). As a consequence of its incorporation of one-way valves, the inter-chamber pipes 280-283 of the PTO illustrated in FIG. 20 need not connect to a receiving chamber at an elevated, raised, and/or relatively high, position relative to the bottom of the receiving chamber. (Each inter-chamber pipe of the PTO illustrated in FIGS. 1-8 connected to its respective receiving chamber at a position near the top of the receiving chamber, and/or at an approximately maximal height above the bottom of the receiving chamber, so as to inhibit or prevent water from flowing backward from the receiving chamber to the originating chamber.)

The illustration in FIG. 20 includes a rectangular plane 288 (i.e. a “deck”) beneath the PTO that is nominally parallel to the resting surface of the body of water on which the embodiment of which the PTO is a part floats, and is provided to assist the reader in evaluating the relative heights of the water-holding chambers on the left and right sides of the PTO.

In response to appropriate directions, magnitudes, and durations of tilting of the PTO illustrated in FIG. 20 (and its associated buoyant embodiment, not shown):

Water flows into and/or enters chamber 289 through inlet pipes 290 and thereafter becomes trapped within that chamber due to the height of the inlet pipes 290 relative to the bottom of the chamber 289.

Water trapped within chamber 289 flows “up” (which is “down” during periods of appropriate tilting) through one-way valve 284 and through inter-chamber pipe 280. The distal (i.e. far from the originating chamber 289) end 291 of inter-chamber pipe 280 enters receiving chamber 292 and the water flowing through that pipe flows into chamber 292 at a position near the bottom of the chamber. Because of the one-way valve 284, the water within chamber 292 is effectively trapped therein and unable to flow backward into chamber 289.

Water trapped within chamber 292 flows “up” (which is “down” during periods of appropriate tilting) through one-way valve 285 and through inter-chamber pipe 281. The distal (i.e. far from the originating chamber 292) end (not visible) of inter-chamber pipe 281 enters receiving chamber 293 and the water flowing through that pipe flows into chamber 293 at a position near the bottom of the chamber. Because of the one-way valve 285, the water within chamber 293 is effectively trapped therein and unable to flow backward into chamber 292.

Water trapped within chamber 293 flows “up” (which is “down” during periods of appropriate tilting) through one-way valve 286 and through inter-chamber pipe 282. The distal (i.e. far from the originating chamber 293) end 294 of inter-chamber pipe 282 enters receiving chamber 295 and the water flowing through that pipe flows into chamber 295 at a position near the bottom of the chamber. Because of the one-way valve 286, the water within chamber 295 is effectively trapped therein and unable to flow backward into chamber 293.

Water trapped within chamber 295 flows “up” (which is “down” during periods of appropriate tilting) through one-way valve 287 and through inter-chamber pipe 283. The distal (i.e. far from the originating chamber 295) end (not visible) of inter-chamber pipe 283 enters receiving chamber 296 and the water flowing through that pipe flows into chamber 296 at a position near the bottom of the chamber. Because of the one-way valve 287, the water within chamber 296 is effectively trapped therein and unable to flow backward into chamber 295.

Water trapped within chamber 296 is at a significantly raised height, elevation, and/or level, than the water that entered chamber 289 through inlet ports 290. It therefore has a significantly greater gravitational potential energy and/or head pressure than when it began its progressive journey to chamber 296. Water trapped within chamber 296 flows out of the chamber through pipe 297 and into and through water turbine 298. The water flowing through water turbine 298 imparts energy to the generator 299 operably connected to the water turbine, thereby generating electrical power. After passing through the water turbine 298, the water that flowed out of chamber 296 flows into and out of effluent pipe 300, thereby returning to the body of water from which it originated, perhaps to again flow into chamber 289 and to again be raised to chamber 296.

The scope of the present invention includes any number, shape, size, and/or volume of water-holding chambers. The scope of the present invention includes any arrangement: horizontal, vertical, and/or spatial, of water-holding chambers, including, but not limited to, the distances between chambers, vertically, horizontally, and/or spatially. The scope of the present invention includes any number, shape, cross-sectional area, diameter, size, length, and/or volume of inter-chamber pipes, within the PTO and/or fluidly connecting any two chambers. The scope of the present invention includes any means, mechanism, device, and/or component, by which the flow of water through the inter-chamber pipes is directed, regulated, adjusted, and/or modified, including, but not limited to, any and every means, mechanism, device, and/or component, by which water is compelled to flow in only a single direction, and/or only toward a respective receiving chamber. The scope of the present invention includes any means, mechanism, device, pipe, aperture, and/or component, by which water is permitted to flow into an initial chamber (e.g., chamber 289 in FIG. 20), including inlet pipes and/or apertures that incorporate one-way valves to prevent water from flowing out of such an initial chamber after having flowed in. The scope of the present invention includes any means, mechanism, device, pipe, aperture, and/or component, by which raised water is directed into, and/or permitted to enter, a water turbine.

FIG. 21 shows a side view of the same power takeoff (PTO) illustrated in FIG. 20. Whereas the inter-chamber pipes, e.g. pipe 108, of the PTO illustrated in FIG. 2 are seen to connect with, and/or enter, their respective receiving chambers, e.g. chamber 107, at an elevated position (relatively high above the bottom of the respective receiving chambers), the corresponding inter-chamber pipes, e.g., pipe 282, of the PTO illustrated in FIGS. 20 and 21 are seen to connect with, and/or enter, their respective receiving chambers, e.g. chamber 295, at a relatively low position, e.g., 294, (relatively near the bottom of the respective receiving chambers). The reduced relative heights above the bottom of the receiving chambers at which the inter-chamber pipes of the PTO illustrated in FIGS. 20 and 21 connect with those respective receiving chambers offers the advantage that a smaller tilt angle can cause water to flow from the originating chamber, e.g., 293, to the relatively higher receiving chamber, e.g., 295, than the tilt angle required of the PTO illustrated in FIGS. 1-8.

FIG. 22 shows a perspective side view of a power takeoff (PTO) characteristic of an embodiment of the present disclosure. The full embodiment of which the illustrated PTO is a part includes a flotation platform (not shown) to which the illustrated PTO is attached and the embodiment floats adjacent to an upper surface of a body of water over which waves pass. Unlike the PTOs illustrated in FIGS. 1-8, FIGS. 9-11, FIGS. 12-14, FIGS. 15-19, and FIGS. 20-21, the water-holding chambers of the PTO illustrated in FIG. 22 are adjacent to one another without any significant distance separating them from one another. An advantage of this PTO is that a tilts of favorable angles and sufficient magnitudes may achieve an uphill flow of water during a significantly shorter period of time, and the tilts that give rise to the uphill flow of water may therefore be of significantly shorter duration than those of the embodiments illustrated in the earlier figures.

In response to appropriate directions, magnitudes, and durations of tilting of the PTO illustrated in FIG. 22 (and its associated buoyant embodiment, not shown):

Water flows into and/or enters chamber 310 through inlet pipes 311. Unlike the inlet pipes of the PTOs illustrated in the earlier figures, the inlet pipes of the PTO illustrated in FIG. 22 include one-way valves which allow water to enter chamber 310 but do not allow it to leave that chamber. Because of the one-way valves that prevent backflow through the inlet pipes, water that enters chamber 310 through the inlet pipes tends to become trapped within that chamber.

Water trapped within chamber 310 flows into chamber 312 through one-way valves that span the wall(s) separating those chambers, the water thereby becoming trapped within chamber 312, and therefore become trapped at an increased height, level, and/or elevation.

Water trapped within chamber 312 flows into chamber 313 through one-way valves that span the wall(s) separating those chambers, the water thereby becoming trapped within chamber 313, and therefore become trapped at an increased height, level, and/or elevation.

Water trapped within chamber 313 flows into chamber 314 through one-way valves that span the wall(s) separating those chambers, the water thereby becoming trapped within chamber 314, and therefore become trapped at an increased height, level, and/or elevation.

Water trapped within chamber 314 flows into chamber 315 through one-way valves that span the wall(s) separating those chambers, the water thereby becoming trapped within chamber 315, and therefore become trapped at an increased height, level, and/or elevation.

And, water trapped within chamber 315 flows out of that chamber and into pipe 316, and therethrough flows into and through water turbine 317, thereby causing the generator 318 operably connected to water turbine 317 to generate electrical power. After engaging and flowing through the water turbine, the water flows into and out of effluent pipe 319 thereby escaping the PTO and nominally returning to body of water from which it originated, perhaps to re-enter chamber 310 through inlets 311 and repeat the wave-to-electrical power conversion cycle again.

FIG. 23 shows a perspective side sectional view of the same power takeoff (PTO) illustrated in FIG. 22 plane wherein the vertical section plane passes through the center of each water-holding chamber and the water turbine.

When the surface of the body of water impinging upon the one-way inlet pipes 311 and valves 320 is higher than the surface of the water within chamber 310, water flows 321 through the one-way inlet pipes 311 and valves 320, enters chamber 310 and, as a consequence of the one-way valves preventing an out flow of water from the chamber, becomes trapped therein.

In response to a tilt of a favorable angle, e.g., within the section plane and in a counter-clockwise direction relative to the PTO orientation illustrated in FIG. 23, a sufficient magnitude, i.e. a sufficient angle within the section plane, and of sufficient duration, i.e. long enough for water to flow, water flows 322 from chamber 310 and flows 323 into chamber 312 by passing through one-way valves 324.

In response to a tilt of a favorable angle, e.g., within the section plane and in a clockwise direction relative to the PTO orientation illustrated in FIG. 23, a sufficient magnitude, i.e. a sufficient angle within the section plane, and of sufficient duration, i.e. long enough for water to flow, water flows 325 from chamber 312 and flows 326 into chamber 313 by passing through one-way valves 327.

In response to a tilt of a favorable angle, e.g., within the section plane and in a counter-clockwise direction relative to the PTO orientation illustrated in FIG. 23, a sufficient magnitude, i.e. a sufficient angle within the section plane, and of sufficient duration, i.e. long enough for water to flow, water flows 328 from chamber 313 and flows 329 into chamber 314 by passing through one-way valves 330.

In response to a tilt of a favorable angle, e.g., within the section plane and in a clockwise direction relative to the PTO orientation illustrated in FIG. 23, a sufficient magnitude, i.e. a sufficient angle within the section plane, and of sufficient duration, i.e. long enough for water to flow, water flows 331 from chamber 314 and flows 332 into chamber 315 by passing through one-way valves 333.

Water deposited within chamber 315 flows 334 into pipe 316 and therethrough into and through water turbine 317. Water flowing out of the water turbine 317 flows into effluent pipe 319, and thereafter flows 335 out of the lower mouth 319 of the effluent pipe, and thereby flows out of the PTO. In one embodiment, the effluent 335 flows back into the body of water on which the buoyant embodiment floats. In another embodiment, the effluent 335 flows into a tank, pool, and/or reservoir, from which the water that flows 321 into the inlet pipes 311 and chamber 310 is drawn. In another embodiment the chambers are separated from those chambers above (if any) and/or below (if any) by a gap and/or space. In another embodiment, the effluent pipe 319 connects directly to chamber 310 thereby depositing the effluent water into that chamber from which it will repeat, and/or begin again, the pattern of incremental lateral and upward flows that will again deposit it within chamber 315.

The scope of the present invention includes any number, shape, size, and/or volume of water-holding chambers. The scope of the present invention includes any arrangement: horizontal, vertical, and/or spatial, of water-holding chambers, including, but not limited to, the distances between chambers, vertically, horizontally, and/or spatially. The scope of the present invention includes any number, shape, cross-sectional area, diameter, and/or size, of inter-chamber apertures and/or one-way valves, within the PTO, its walls, and/or fluidly connecting any two chambers. The scope of the present invention includes any means, mechanism, device, and/or component, by which the flow of water through the inter-chamber pipes is directed, regulated, adjusted, and/or modified, including, but not limited to, any and every means, mechanism, device, and/or component, by which water is compelled to flow in only a single direction, and/or only toward a respective receiving chamber. The scope of the present invention includes any means, mechanism, device, pipe, aperture, and/or component, by which water is permitted to flow into an initial chamber (e.g., chamber 289 in FIG. 20), including inlet pipes and/or apertures that incorporate one-way valves to prevent water from flowing out of such an initial chamber after having flowed in. The scope of the present invention includes any means, mechanism, device, pipe, aperture, and/or component, by which raised water is directed into, and/or permitted to enter, a water turbine. The scope of the present invention includes any type, design, variety, size, and/or volume, of water turbine. The scope of the present invention includes any type, design, variety, size, and/or rated power, of generator and/or alternator. The scope of the present invention includes any means, mechanism, device, system, module, and/or component, by which generated electrical power is stored.

FIG. 24 shows a perspective side view of a pair of water-holding chambers 350 and 351 that constitute an element of a power takeoff (PTO) characteristic of an embodiment of the present disclosure. The PTO of which the illustrated element is a part would typically be mounted to a buoyant platform and when floating adjacent to an upper surface of a body of water and that buoyant platform, and the PTO attached to it, would respond to waves passing beneath the embodiment by tilting.

Water-holding chamber 350 is at a lower height within the PTO of which it is a part. In a resting embodiment that is not moving, chamber 350 is at a lesser height above the surface of the body of water on which the embodiment floats, and/or is at a greater depth below that surface, than is chamber 351. Water will not spontaneously flow from chamber 350 to chamber 351 except in response to a tilt of a favorable direction, i.e. a tilt that raises chamber 350 and/or lowers chamber 351, sufficient magnitude, i.e. a tilt big enough to cause chamber 351 to be partially or fully below chamber 350 relative to their heights above the mean height of the surface of the body of water, and of sufficient duration, i.e. long enough to allow water to flow over the distance that separates chambers 350 and 351.

Chamber 350 is fluidly connected to chamber 351 by inter-chamber pipe 352. Inter-chamber pipe 352 connects to chamber 350 near its lowermost chamber wall. Inter-chamber pipe 352 connects to chamber 351 near its uppermost chamber wall. Because of the low connection point of inter-chamber pipe 352 to chamber 350, water from within chamber 350 will tend to immediately flow into that pipe with the chamber and pipe are subjected to a favorable tilt. Because of the high connection point of inter-chamber pipe 352 to chamber 351, water that flows into chamber 351 from chamber 350 will tend to be trapped within chamber 351 and unable to flow back into pipe 352 and back to chamber 350.

Inter-chamber pipe 352 follows a circumferential path from an outer wall (a wall furthest from the center about which chambers 350 and 351 are arrayed) of chamber 350 to an outer wall of chamber 351.

FIG. 25 shows a top-down view of the same pair of water-holding chambers 350 and 351 illustrated in FIG. 24.

FIG. 26 shows a side sectional view of the same pair of water-holding chambers 350 and 351 illustrated in FIGS. 24 and 25 wherein the vertical section plane is specified in FIG. 25 and the section is taken across line 26-26.

Relative to a resting, and/or nominally oriented embodiment and PTO, chamber 351 is positioned at a greater height 355 than is chamber 350. And, inter-chamber pipe 352 connects to chamber 350 at a relatively bottom-most position 353 while connecting to chamber 351 at a relatively upper-most position 354. When the PTO of which the illustrated pair of water-holding chambers are a part must tilt to an angle 356 then, if there is water within chamber 350 and there is room to accommodate additional water within chamber 351, water to flow from chamber 350 to chamber 351 through pipe 352. However, water will also flow if, when, and for as long as, the tilt of the associated PTO and embodiment reaches or exceeds the lesser angle characteristic of a line intersecting an upper surface of the water within chamber 350 and the aperture 354 through which inter-chamber pipe 352 connects with chamber 351.

FIG. 27 shows a perspective side view of a pair of water-holding chambers 350 and 357 that constitute an element of a power takeoff (PTO) characteristic of an embodiment of the present disclosure. The PTO of which the illustrated element is a part would typically be mounted to a buoyant platform and when floating adjacent to an upper surface of a body of water and that buoyant platform, and the PTO attached to it, would respond to waves passing beneath the embodiment by tilting.

Whereas chamber 350 was fluidly connected to chamber 351 by an inter-chamber pipe 352 that followed a circumferential path outside and adjacent to a circular boundary that passes through the outer walls of chambers 350 and 351, the water-holding chambers 350 and 357 are fluidly connected to one another by an inter-chamber pipe 358 that follows a circumferential path inside and adjacent to a circular boundary that passes through the inner walls of chambers 350 and 357. As was the case for the inter-chamber pipe 352 that permits water to flow from chamber 350 to chamber 351, the inter-chamber pipe 358 is connected to chamber 350 at a low position 359, adjacent to a lower and/or bottom wall of chamber 350; and it is connected to chamber 357 at a high position 360, adjacent to an upper and/or top wall of chamber 357—thus water that has flowed from chamber 350 into chamber 357 will be unlikely or unable to flow back into inter-chamber pipe 358 and therethrough back to chamber 350.

FIG. 28 shows a top-down view of the same pair of water-holding chambers 350 and 357 illustrated in FIG. 27.

FIG. 29 shows a side sectional view of the same pair of water-holding chambers 350 and 357 illustrated in FIGS. 27 and 28 wherein the vertical section plane is specified in FIG. 28 and the section is taken across line 29-29.

Relative to a resting, and/or nominally oriented embodiment and PTO, chamber 357 is positioned at a greater height 361 than is chamber 350. And, inter-chamber pipe 358 connects to chamber 350 at a relatively bottom-most position 359 while connecting to chamber 357 at a relatively upper-most position 360. When the PTO of which the illustrated pair of water-holding chambers are a part must tilt to an angle 362 then, if there is water within chamber 350 and there is room to accommodate additional water within chamber 357, water to flow from chamber 350 to chamber 357 through pipe 358. However, water will also flow if, when, and for as long as, the tilt of the associated PTO and embodiment reaches or exceeds the lesser angle characteristic of a line intersecting an upper surface of the water within chamber 350 and the aperture 360 through which inter-chamber pipe 358 connects with chamber 357.

FIG. 30 shows a perspective side view of the same three inter-connected water-holding chambers 350, 351, and 357, that are illustrated as separate pairs of chambers in FIGS. 24-26 and FIGS. 27-29. The three inter-connected chambers and their respective inter-chamber pipes constitute an element of a power takeoff (PTO) characteristic of an embodiment of the present disclosure. The PTO of which the illustrated element is a part would typically be mounted to a buoyant platform and when floating adjacent to an upper surface of a body of water and that buoyant platform, and the PTO attached to it, would respond to waves passing beneath the embodiment by tilting.

Upper chambers 351 and 357 are at approximately the same height above, and/or vertical distance from, lower chamber 350. In response to a wave-induced tilting of the PTO configuration illustrated in FIG. 30 of favorable direction, magnitude, and duration, water will tend to flow from chamber 350 to chamber 351 through inter-chamber pipe 352, and simultaneously flow from chamber 350 to chamber 357 through inter-chamber pipe 358.

FIG. 31 shows a perspective side view of the same three inter-connected water-holding chambers 350, 351, and 357, that are illustrated in FIG. 30. Note that chambers 351 and 357 are at a greater height and/or elevation than is chamber 350. And, because of this, water will only tend to flow from chamber 350 to chambers 351 and 357 in response to a wave-induced tilt of the PTO of a favorable angle, sufficient magnitude, and sufficient duration.

FIG. 32 shows a perspective side view of two levels of water-holding chambers arrayed in concentric circular patterns about a common vertical longitudinal axis. Eight chambers, e.g., 350 and 363, on the lower level, i.e. the level that would be characterized by the least height (the least positive height or the greatest negative height) relative to the resting surface of a body of water on which a power takeoff (PTO) comprised in part of the chambers and an attached buoyant platform might float, are rotationally and/or angularly offset by approximately one-half the width of a chamber from eight chambers, e.g., 351, 357, and 364, on an upper that would be characterized by a greater height than those of the lower level. Chamber 350 of the lower level, and chambers 351 and 357 of the upper level, have the same relative spatial orientations, placements, separation distances, and positions, as illustrated in FIGS. 24-31.

FIG. 33 shows a perspective side view of the same two levels of water-holding chambers illustrated in FIG. 32. However, in FIG. 33, those chambers have been interconnected in the manner illustrated in FIGS. 24-31.

Each of the eight chambers, e.g. chamber 350, on the lower level is connected to a pair of adjacent chambers, e.g., chambers 351 and 357 respectively, on the upper level. One connection of each chamber on the lower level, e.g., chamber 350, is established through an outer circumferential inter-chamber pipe, e.g., pipe 352. And, the other connection of each chamber on the lower level, e.g., chamber 350, is by way of an inner circumferential inter-chamber pipe, e.g., pipe 358.

FIG. 34 shows a top-down view of the same two levels of inter-connected water-holding chambers illustrated in FIG. 33.

FIG. 35 shows a side sectional view of the same two levels of inter-connected water-holding chambers illustrated in FIGS. 33 and 34, wherein the vertical section plane is specified in FIG. 34 and the section is taken across line 35-35.

FIG. 36 shows a perspective side view of a power takeoff (PTO) characteristic of an embodiment of the present disclosure. The full embodiment of which the illustrated PTO is a part includes a flotation platform (not shown) to which the illustrated PTO is attached and the embodiment floats adjacent to an upper surface of a body of water over which waves pass.

The PTO illustrated in FIG. 36 is comprised of nine levels of water-holding chambers similar to the two levels of water-holding chambers illustrated in FIGS. 32-35. Each chamber on the first and/or lowest eight levels is fluidly connected to two chambers on the next highest level radially positioned approximately opposite each respective lower-level chamber. Each chamber on the first and/or lowest eight levels is fluidly connected to a first of two radially-opposing chambers on the next highest level by a circumferential inter-chamber pipe positioned outside the concentric levels of radially-positioned chambers. And, each chamber on the first and/or lowest eight levels is fluidly connected to a second of two radially-opposing chambers on the next highest level by a circumferential inter-chamber pipe positioned inside the concentric levels of radially-positioned chambers.

The relationship of each chamber on each of the first and/or lowest eight levels of the PTO to the chambers on the respective next highest levels, and the inter-connections between the chambers on each level of the PTO to the chambers on the adjacent levels of the PTO is the same as illustrated in FIGS. 33 and 35.

Each water-holding chamber, e.g., 370, in the lowest-level of the PTO, includes an inlet pipe, e.g., 371, through which water may flow 372 into each respective lowest-level chamber, from which a succession of favorable tilts, of adequate magnitude and duration, may raise that water from chamber to chamber, and from level to level, through the circumferential array of inter-chamber pipes, some wrapping around the outside the cylindrical array of chambers, e.g., 373, and some wrapping around the inside of the cylindrical array of chambers, e.g., 374, that connect each chamber within the PTO to at least one other chamber on a different level, until the water is deposited within a chamber in the uppermost level of the PTO, e.g. 375-377.

Each water-holding chamber, e.g., 375-377, at the uppermost level of the PTO, includes a pipe, e.g., 378, through which water may flow out of the respective upper chamber and therethrough flow into and through a water turbine, e.g., 379, thereby imparting energy to a respective operably connected generator, e.g., 380. Water flowing out of each water turbine id directed into a respective effluent pipe, e.g., 381, through and from which it flows 382 out of the PTO. In one embodiment, the water flowing out of the embodiment's PTO flows back into the body of water on which the embodiment floats and from which the water entering the chambers on the lowest level of the PTO is drawn. In another embodiment, the water flowing out of the embodiment's PTO flows into a reservoir and thereafter tends to reenter a chamber on the lowest level of the PTO and repeat the cycle of flows that will again raise it to the upper level and again deposit it into a chamber on the upper level from which it will again energize a water turbine and an operably connected generator.

While the PTO illustrated in FIG. 36 contains nine levels of chambers, the scope of the present invention includes PTOs with any number of levels. And, while the chambers of each level within the PTO illustrated in FIG. 36 are concentric about a common vertical longitudinal axis of the PTO, and are positioned at the same relative height with respect to the base of the PTO, the scope of the present invention includes PTOs with any positional arrangement of chambers within a level, and with any vertical offsets of chambers within any particular level. The scope of the present invention includes PTOs with any number of chambers in a level, any number of levels of chambers, any radial separation of the chambers within a level, any spatial orientation, spacing, separations, and/or arrangement, of chambers within a level and/or within a PTO. The scope of the present invention includes PTOs with chambers of any size, chambers of differing sizes, chambers of any volume, and chambers of differing volumes. The scope of the present invention includes PTOs with chambers inter-connecting with any number of other chambers on different levels of the PTO and/or on the same level of the PTO. The scope of the present invention includes PTOs in which any particular chamber within the PTO is connected to any other chamber on the same or a different level by any number of pipes. The scope of the present invention includes PTOs in which any particular chamber within the PTO is connected to any other chamber on the same or a different level by one or more pipes containing, incorporating, and/or utilizing, any mechanism, manner, means, device, and/or valve, to regulate, control, adjust, direct, and/or alter, the pattern of flow within the pipe(s), including, but not limited to, the creation of one-way flows.

The scope of the present invention includes PTOs with any arrangement of inter-chamber pipes, any number of such pipes, any pipe diameters, any pipe cross-sectional areas, any pipe lengths, any pipe shapes, and any pipe couplings.

FIG. 37 shows a side sectional view of the same power takeoff (PTO) illustrated in FIG. 36, wherein the vertical section plane passes through a central vertical longitudinal axis of approximate radial symmetry.

FIG. 38 shows a perspective side view of an embodiment of the present disclosure that incorporates the power takeoff (PTO) illustrated in FIGS. 36 and 37.

The approximately cylindrical PTO 383 is positioned within, and attached to, an approximately cylindrical buoy 384, buoyant structure, flotation module, vessel, and/or float. The embodiment incorporating the PTO 383 floats adjacent to an upper surface 385 of a body of water over which waves tend to pass. The waves buffet the embodiment, thereby causing the PTO 383 within the embodiment to tilt in a variety of directions, for a variety of durations, and thereby tending to cause the water within the PTO to be progressively and/or incrementally lifted until it spills out and through the PTO's water turbines, thereby generating electrical power.

FIG. 39 shows a top-down view of the same embodiment of the present disclosure that is illustrated in FIG. 38.

Water that flows into the water turbines through pipes, e.g., 378, and flows through the respective water turbines, e.g., 379, is subsequently discharged from the effluent pipes of those water turbines and deposited into a water reservoir 386 between the exterior of the power takeoff (PTO) 383 and the inner wall of the cavity within the buoy 384 within which the PTO is positioned. Water within the reservoir 386 flows into the PTO's inlet apertures, e.g., 371, and is again lifted through the PTO's water-holding chambers, in response to wave-induced tilting, until it is again released from the PTO's upper level and directed through one of the PTO's water turbines to again generate electrical power.

The water (or other fluid) that flows through the PTO is repeatedly deposited into the embodiment's water reservoir 386 and therefrom repeatedly recycled and/or recirculated through the PTO.

FIG. 40 shows a side perspective sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 38 and 39 wherein the vertical section plane is specified in FIG. 39 and the section is taken across line 40-40. After its discharge (382 in FIG. 37) from a water turbine's effluent tube (381 in FIG. 37), water accumulates and is stored in the embodiment's water reservoir 386, until it again enters (372 in FIG. 37) an inlet aperture (371 in FIG. 37), is again lifted within the PTO, and is again discharged from a water turbine's effluent tube.

FIG. 41 shows a perspective side view of a power takeoff (PTO) characteristic of an embodiment of the present disclosure. The full embodiment of which the illustrated PTO is a part includes a flotation platform (not shown) to which the illustrated PTO is attached and floats adjacent to an upper surface of a body of water over which waves pass.

Although not required for its manufacture or operation, the PTO illustrated in FIG. 41 is comprised of a number of interleaved outer and inner layers. The six outer layers 400-405 are stacked with adjacent upper and lower surfaces. They are arrayed so as to be coaxial about a common vertical longitudinal axis, that is also an axis of approximate radial symmetry. Between each pair of adjacent outer layers is interleaved an inner layer (not visible) which is also positioned so as to be coaxial about the same common vertical longitudinal axis about which the outer layers are arrayed.

The bottommost outer layer 400 includes eight inlet apertures, e.g., 406, each of which is defined by a respective structural frame, e.g., 407, through which water flows 408 into an annular reservoir (not visible) of the bottommost layer.

A tilting motion of the PTO, and the embodiment to which it is attached, of favorable direction, and sufficient magnitude and duration, causes a portion of the water in the annular reservoir of the bottommost outer layer 400 to flow into a reservoir at the center of the adjacent and bottommost inner layer (not visible) that is positioned between outer layers 400 and 401. Successive tilting motions of the PTO, and the embodiment to which it is attached, of favorable direction, and sufficient magnitude and duration, cause water to rise by flowing from annular reservoirs (in outer layers) to central reservoirs (in interleaved inner layers), and then from central reservoirs to annular reservoirs.

After a sufficient number of sufficient tilting motions, water reaches the annular reservoir of the uppermost layer 405 from which it flows into one of two turbine reservoirs 409 and 410, and therefrom into and through two effluent pipes 411 and 412. In one embodiment, water exiting the effluent pipes, e.g., 413, flows back into the body of water on which the embodiment floats, and from which water flows, e.g., 408, into the PTO. In another embodiment, water exiting the effluent pipes, e.g., 413, flows into a reservoir of water external to the PTO, but internal to the embodiment of which it is a part, and water flowing, e.g., 408, into the PTO is drawn from that same reservoir, thereby making the PTO, with respect to its water, a closed and/or recirculating system.

Within each effluent tube 411 and 412 is a respective water turbine (not visible) that is operably connected to a respective generator 414 and 415 by a respective shaft 416 and 417. The interleaved arrays of outer and inner layers, and their respective annular and central reservoirs, are covered by an upper surface 418 that, at least partially, e.g., from above, separates the PTO's internal reservoirs from the atmosphere and/or from the rest of the embodiment. The bottommost outer layer 400 contains inlet apertures, e.g., 406, but is otherwise also, at least partially, separated from the ambient environment and/or from the rest of the embodiment. In one embodiment, water enters, e.g., 408, the PTO through an inlet aperture, e.g., 406, and leaves, e.g., 413, through an effluent tube 411 and 412, but is otherwise trapped within the PTO.

Water from outside the PTO enters 408 the PTO through one of the eight inlet apertures, e.g., 406, positioned near its base, and within its bottommost outer layer (400 in FIG. 41). In response to a tilt of the PTO of favorable direction, magnitude, and duration, water flowing 408 in through an inlet aperture, e.g., 406, flows 419 up one of the PTO's eight annular ramps, e.g., 420, each of which allows water to flow from the annular reservoir of an outer layer toward the center of the PTO. A “waterfall edge” (i.e., an edge of an upper surface, such as a ramp, that is raised relative to an adjacent lower surface, and/or void, such that a fluid flowing from the upper surface and over the waterfall edge will tend to fall and/or flow downward onto the lower surface) at the end of an annular ramp, e.g., 421, tends to cause water flowing, e.g., 422, toward the end 421 of the ramp to “fall over” the ramp's edge 421 and fall 423 into, and become trapped within, a reservoir 424 at the center of the bottommost inner layer. So, in response to a tilt of the PTO of favorable direction, magnitude, and duration, water flowing in through an inlet aperture tends to flow up and down into a reservoir at the center of the PTO, the elevation and/or height of which is greater than that of the inlet aperture.

In response to a tilt of the PTO of favorable direction, magnitude, and duration, water trapped within the central reservoir 424 of the bottommost inner layer flows, e.g., 425, up a ramp, e.g., 426, and over its waterfall edge, thereby falling into the annular reservoir, e.g., 427, of the next highest outer layer (401 in FIG. 41).

Likewise, and in serial fashion, in response to tilts of the PTO of favorable directions, magnitudes, and durations, water flows:

from annular reservoir 427 up ramp 428 toward the waterfall edge at its centermost edge until it approaches 429 and falls over 430 that edge into the central reservoir 431 of the second (from the bottom) inner layer;

from central reservoir 431 up 432 and over waterfall edge 433 thereby falling into the annular reservoir 434 of the third (from the bottom) outer layer (402 in FIG. 41);

from annular reservoir 434 up ramp 435 toward the waterfall edge at its centermost edge until it approaches 436 and falls over 437 that edge into the central reservoir 438 of the third (from the bottom) inner layer;

from central reservoir 438 up 439 and over waterfall edge 440 thereby falling into the annular reservoir 441 of the fourth (from the bottom) outer layer (403 in FIG. 41);

from annular reservoir 441 up ramp 442 toward the waterfall edge at its centermost edge until it approaches 443 and falls over 444 that edge into the central reservoir 445 of the fourth (from the bottom) inner layer;

from central reservoir 445 up 446 and over waterfall edge 447 thereby falling into the annular reservoir 448 of the fifth (from the bottom) outer layer (404 in FIG. 41);

from annular reservoir 448 up ramp 449 toward the waterfall edge 450 at its centermost edge until it approaches 451 and falls over 452 that edge into the central reservoir 453 of the fifth (from the bottom) inner layer; and,

from central reservoir 453 up 454 and over waterfall edge 455 thereby falling 457 into the annular reservoir 456 of the sixth and uppermost outer layer (405 in FIG. 41).

Water deposited into, and/or trapped within, the annular reservoir 456 of the uppermost outer layer (405 in FIG. 41) is then directed into one of two turbine reservoirs, e.g., 410, where that water 458 then flows 413 into, and through, effluent tube 411 wherein it flows through, energizes, and causes to rotate, a water turbine 459, which, in turn, causes the operably connected generator 414 to generate electrical power. After passing through the water turbine 459, water flowing through effluent tube 411 exits 413 through a mouth 460 at the bottom end of the effluent tube 411.

FIG. 45 shows a top-down view of the structure of which the bottommost outer layer (400 in FIG. 41) is comprised. The structural component illustrated in FIG. 45 is shown separate from the other inner and outer layers of the power takeoff (PTO) illustrated in FIGS. 41-44. The layer is comprised of eight inlet apertures, e.g., 406 and 461. A vertical inlet dividing wall, e.g., 462-464, divides the water entering each inlet aperture. Each inlet dividing wall likewise divides the layer's 400 annular reservoir into eight segments, e.g., 465-467. Water entering, e.g., 408A, the layer's annular reservoir to one side of an inlet aperture's dividing wall, e.g., 463, is added to one reservoir segment, e.g., 467, while water entering, e.g., 408B, to the other side of the inlet aperture's dividing wall, e.g., 463, is added to an adjacent reservoir segment, e.g., 466.

The layer's annular reservoir is fluidly connected to eight annular ramps, e.g., 468-470, that permit water within the annular reservoir's eight annular reservoir segments, e.g., 465-467, to flow up and into a central reservoir of an inner layer when that reservoir is positioned beneath the waterfall and/or centermost ends, e.g., 471, of the annular ramps. The water within any particular segment, e.g., 467, of the layer's annular reservoir is able to flow up either of two respective fluidly connected ramps, e.g., 469 and 470. For instance, water entering 472 inlet aperture 461 below inlet aperture dividing wall 464 will flow into annular reservoir segment 467 and from there will be able to flow up either of annular ramps 469 or 470. Likewise, water entering 408A inlet aperture 406A above inlet aperture dividing wall 463 will also flow into annular reservoir segment 467 and from there will also be able to flow up either of annular ramps 469 or 470.

Adjacent segments, e.g., 465 and 466, of the layer's annular reservoir are not completely separated. In response to a particular motion of the layer 400, the PTO of which it is a part, and/or the embodiment of which the PTO is a part, can send water from one segment, e.g., 466, up and around 473 an inlet aperture dividing wall, e.g., 462, and into an adjacent segment, e.g., 465, of the annular reservoir.

Each annular ramp, e.g., 469, is bounded, bordered, and/or constrained, by a respective pair of lateral walls, e.g., 474 and 475. Between each pair of adjacent annular ramps, e.g., 468 and 469, is a sloping bottom wall, e.g., 476, that shares the same up-tilted surface(s) of which the annular ramps are comprised. An open portion 477 of the bottom wall at the center of the layer provides space into which the central reservoir of an inner layer can fit and/or be placed. The bottom surface of such a positioned inner layer will block the centermost edge, e.g., 478, of each inter-annular-ramp portion of each segment of the annular reservoir.

FIG. 46 shows a perspective side view of the same bottommost outer layer (400 in FIG. 41) illustrated in FIG. 45.

FIG. 47 shows a top-down view of the structure of which each of the power takeoff's (PTO's) five inner layers is comprised. The structural component illustrated in FIG. 47 is shown separate from the other inner and outer layers of the power takeoff (PTO) illustrated in FIGS. 41-46.

Each inner layer is comprised of an approximately flat central reservoir 479 at the base of an approximately frustoconical and/or upwardly inclined radial array of eight ramps, e.g., 480. Each central ramp, e.g., 480, is bounded, defined, and/or constrained, by a respective pair of lateral walls, e.g., 481 and 482. Water contained, constrained, and/or pooled, within the layer's central reservoir 479, can, e.g., in response to a tilt of favorable direction, and sufficient magnitude and duration, flow away from the reservoir's center and radially outward up one of the central ramps, e.g., 480. At the distal end of each central ramp, e.g., 480, is a “waterfall” edge, e.g., 483. When positioned within the complete, multi-layer PTO, water flowing over the distal waterfall edge of a central ramp, tends to fall into, and become trapped within, an annular reservoir, and/or a segment thereof (e.g., 467 in FIGS. 45 and 46).

Between the central reservoir 479 and the upwardly inclined surfaces of which the central ramps, e.g., 480, are in part comprised there may be a discernable bend and/or fold 484 that delineates their junction.

Between each pair of adjacent central ramps, e.g., 480 and 485, is an unwalled edge, e.g., 486. The bottom of an upwardly inclined annular ramp (e.g., 470 of FIGS. 45 and 46) of an outer layer abuts each inter-central-ramp edge, e.g., 486, thereby preventing the flow of water across those edges, and otherwise trapping water within the respective central reservoir 479.

In a similar embodiment, the central reservoir 479 is concave, e.g., with a downward depression, thereby comprising an approximately bowl-shaped cavity in which water may be held until induced to flow by a tilt of favorable direction and sufficient magnitude and duration.

FIG. 48 shows a perspective side view of the same inner layer illustrated in FIG. 47.

FIG. 49 shows a top-down view of the structure of which each of the power takeoff's (PTO's) four middle outer layers (401-404 in FIG. 41) is comprised. The structural component illustrated in FIG. 49 is shown separate from the other inner and outer layers of the power takeoff (PTO) illustrated in FIGS. 41-48. The illustrated outer layer structure differs from the bottommost outer layer (400 in FIG. 41), which is adapted to allow water to enter the PTO, and the uppermost outer layer (405 in FIG. 41), which is adapted to divert water from its annular reservoir into two turbine reservoirs.

An approximately flat-bottomed annular ring is divided into eight radial segments, e.g., 487-489, by eight interposed radially-oriented walls, e.g., 490 and 491. Straddling each dividing wall is an annular ramp, e.g., 492 and 493. Each of dividing wall, e.g., 491, extends up its respective annular ramp, e.g., 493, a short distance, however, in response to a tilt, especially an incomplete tilt, and/or an anomalous pattern of water flow within the annular reservoir, water can flow from one annular reservoir segment, e.g., from 488, to the neighboring segment, e.g., to 489, by flowing up and around the intervening dividing wall, e.g., 491. In general, each dividing wall, e.g., 491, directs water from each of the adjacent annular reservoir segments, e.g., 488 and 489, on either side to flow into and up the respective annular ramp, e.g., 493.

Each annular ramp has a bottom surface that is upwardly inclined. The seam and/or junction, e.g., 494, at which each upwardly inclined annular ramp, e.g., 492, is connected to its respective pair of approximately flat-bottomed annular reservoir segments, e.g., 487 and 488, is indicated by a circular line, e.g., 494, and/or fold at the distal end of each ramp. At the innermost edge, e.g., 495, of each annular reservoir segment, e.g., 489, and positioned between each segment's connected pair of annular ramps, e.g., 493 and 496, is a wall, e.g., 495, that is shorter than the lateral walls, e.g., 497 and 498, of the adjacent annular ramps, e.g., 493 and 496. The top of this shorter annular reservoir wall, e.g., 495, abuts with the bottom of a central ramp (e.g., 480 of FIGS. 47 and 48) of an inner layer immediately below the illustrated outer layer.

At the side of each annular ramp, e.g., 492, is a side wall, e.g., 499 and 500, that constrains and guides water flowing up (or, in response to a favorable tilt, down) the respective annular ramp, e.g., 492. At the centermost end of each annular ramp, e.g., 492, is a waterfall edge, e.g., 501, over which water flows off of the annular ramp and falls into the central reservoir of an inner layer immediately below the respective outer layer.

Around the outer perimeter of each outer layer is a circular wall 502 that prevents the leakage of water from the layer's annular reservoir, and/or the segments, e.g., 487-489, thereof.

FIG. 50 shows a perspective side view of the same outer layer illustrated in FIG. 49.

FIG. 51 shows a top-down view of the power takeoff's (PTO's) uppermost outer layer (405 in FIG. 41). The outer layer illustrated in FIG. 51 is shown separate from the other inner and outer layers of the power takeoff (PTO) illustrated in FIGS. 41-50. The illustrated uppermost outer layer structure differs from the intermediate outer layers (401-404 in FIG. 41), in that it is adapted to divert water from its annular reservoir, the last stage in the tilt-induced lifting of water within the PTO, into two turbine reservoirs 409 and 410.

The uppermost outer layer illustrated in FIG. 51 is, in order to promote understanding, shown without its upper surface, ceiling, wall, and/or top, which isolates, at least in part, the water within the PTO from the environment.

The uppermost outer layer's annular reservoir is defined, and water therein is trapped and/or constrained, in part by bottom surfaces 504/505, and a side wall 503. The uppermost outer layer's annular reservoir is divided into two segments, 504 and 505. These two annular reservoir segments are divided, and/or separated from one another, by two dividing walls 506 and 507.

Water deposited into either segment of the annular reservoir 504/505 is diverted, e.g., in response to a tilt-induced flow of water about the annular reservoir, into turbine reservoir 508, located within turbine reservoir enclosure 409, by dividing wall 506, and into turbine reservoir 509, located within turbine reservoir enclosure 410, by dividing wall 507.

Water within turbine reservoir 508 flows down through an effluent tube (not visible, 412 in FIG. 41) thereby engaging and energizing a water turbine (not visible) therein, and causing generator 415, which is operably connected to the water turbine, to generate electrical power. Likewise, water within turbine reservoir 509 flows down through an effluent tube (not visible, 411 in FIG. 41) thereby engaging and energizing a water turbine (not visible, 459 in FIG. 44) therein, and causing generator 414, which is operably connected to the water turbine, to generate electrical power.

Because it is the uppermost outer layer, the illustrated outer layer (405 in FIG. 41) does not have annular ramps to further elevate water within its annular reservoir 504/505. Instead it has innermost side walls, e.g., 510, that extend up to its upper and/or top wall (not shown). As is the case for the intermediate outer layers, the uppermost upper layer illustrated in FIG. 51, has short walls, e.g., 511 (and 495 in FIG. 49), at those portions of the inner edge of its annular reservoir that would otherwise be between annular ramps. The short inner walls of the annular reservoir abut the bottom surfaces of the corresponding central ramps that, within the PTO, lift water from the central reservoir of the inner layer within the PTO that is positioned immediately below the illustrated uppermost outer layer.

FIG. 52 shows a perspective top-down view of the same uppermost outer layer illustrated in FIG. 51.

FIG. 53 shows a top-down sectional view of the same power takeoff (PTO) illustrated in FIGS. 41-44, wherein the horizontal section plane is specified in FIG. 42 and the section is taken across line 53-53.

The section illustrated in FIG. 53 shows the inside of the uppermost outer layer (405 in FIG. 41) as well as the inner layer immediately below. In response to a tilt of favorable direction, and sufficient magnitude and duration, water held in the annular reservoir 512 of the outer layer (404 in FIG. 41) immediately below and adjacent to the uppermost outer layer will flow 513 up (which because of the tilt is actually “down”) annular ramp 514 until it flows 515 over the waterfall edge, e.g., 515 of annular ramp 516, at the central end of ramp 514, thereby falling down and into the central reservoir 479 of the uppermost inner layer that is positioned immediately above the outer layer (404 in FIG. 41) immediately below and adjacent to the uppermost outer layer, and immediately below the uppermost outer layer (405 in FIG. 41).

In response to a tilt of favorable direction, and sufficient magnitude and duration, water held in the central reservoir 479 of the uppermost inner layer flows 518 up (which because of the tilt is actually “down”) central ramp 519 until it flows 520 over the waterfall edge 521 of that central ramp 519, thereby falling into the annular reservoir segment 505 of the uppermost outer layer (405 if FIG. 41). Likewise, in response to a tilt of favorable direction, and sufficient magnitude and duration, (perhaps the same favorable tilt causing water to flow up central ramp 519) water held in the central reservoir 479 of the uppermost inner layer flows up central ramp 527 until it flows over the waterfall edge at the distal and/or outermost end of that central ramp, thereby falling into the annular reservoir segment 505 of the uppermost outer layer (405 if FIG. 41).

In response to a tilt of favorable direction, and sufficient magnitude and duration, water deposited into annular reservoir segment 505 flows 522 in a counterclockwise direction (relative to the orientation of the illustration in FIG. 53), guided and/or constrained by the lateral reservoir walls 503 and 512, until it is obstructed by radial dividing wall 507 after which it flows 522 over a waterfall edge 523 into the turbine reservoir 509 within the turbine reservoir wall 410. Water within the turbine reservoir 509 flows into and down effluent pipe 411 thereby imparting rotational kinetic energy and/or a torque to the water turbine (459 in FIG. 44) therein, thereby causing the attached turbine shaft 416 to rotate, and thereby causing an operably connected generator (414 in FIG. 41) to generate electrical power.

In response to a tilt of favorable direction, and sufficient magnitude and duration, water deposited into annular reservoir segment 505 flows 524 in a clockwise direction (relative to the orientation of the illustration in FIG. 53), guided and/or constrained by the lateral reservoir walls 503 and 512, until it is obstructed by radial dividing wall 506 after which it flows 525 over a waterfall edge 526 into the turbine reservoir 508 within the turbine reservoir wall 409. Water within the turbine reservoir 508 flows into and down effluent pipe 412 thereby imparting rotational kinetic energy and/or a torque to a water turbine therein, thereby causing an attached turbine shaft 417 to rotate, and thereby causing an operably connected generator (415 in FIG. 41) to generate electrical power.

Similarly, in response to a tilt of favorable direction, and sufficient magnitude and duration, water held in the central reservoir 479 of the uppermost inner layer flows up at least one of central ramps 528-534 until it flows over the waterfall edges of those central ramps, thereby falling into the annular reservoir segment 504 of the uppermost outer layer (405 if FIG. 41). And, in response to a tilt of favorable direction, and sufficient magnitude and duration, water deposited into annular reservoir segment 504 flows within the annular reservoir segment 504, guided and/or constrained by the lateral reservoir walls 503 and 512, until it is obstructed by either or both radial dividing walls 506 and 507 after which it flows into one or both of the turbine reservoirs 508 and 509, thereby resulting in the generation of electrical power.

Vertically aligned with the annular reservoir dividing walls, e.g., 506, are the annular reservoir dividing walls, e.g., 534, of the outer layer (404 in FIG. 41) below and adjacent to the uppermost outer layer (405 in FIG. 41), that extend a distance up their respective annular ramps, e.g., 535.

FIG. 55 shows a side view of a schematic/functional illustration of the same power takeoff (PTO) illustrated in FIGS. 41-54. The full embodiment of which the illustrated PTO is a part includes a flotation platform (not shown) to which the illustrated PTO is attached and floats adjacent to an upper surface of a body of water over which waves pass.

The base and/or bottom surface 536 of the PTO corresponds to the bottom of the bottommost outer layer (400 in FIG. 41) of the PTO. When the PTO, and the floating embodiment to which it is attached, are tilted 537, in response to a wave passing across the surface of the body of water on which the embodiment (not shown) to which the PTO is attached, the orientation of the PTO is altered and rotated through an angle 537 from the horizontal (e.g., from the resting surface of the body of water) 538.

In response to the illustrated tilt of the PTO, the annular reservoir segments 539-544 of the PTO's six outer levels (400-405 in FIG. 41) are lifted and/or elevated relative to the central reservoirs 548-552. Because the angle 537 of the tilt exceeds the angle 545 of each annular ramp originating at each respective elevated annular reservoir segment 539-543, water held, deposited, and/or trapped, within each elevated annular segment 539-543 flows, e.g., 546, “up” (which, with respect to gravity is “down” due to the tilt 537) each segment's respective annular ramp, and over each annular ramp's respective waterfall edge, e.g., 547, thereby falling down and into the respective central reservoir 548-552 immediately adjacent to, and “above” (which, with respect to the tilt 537 is actually “below”), each respective outer layer's elevated annular reservoir segment 539-543.

Each of the boxes 548-552 at the center of the PTO illustration in FIG. 55 represents the central reservoir of each of the PTO's inner layers. Note that the height 553 of the bottom 554 of the bottommost central reservoir 548 (where “height” is relative to an axis normal to the bottom 536 of the bottommost outer layer, 400 in FIG. 41, of the PTO), is greater than the height 555 of the bottom 556 of the bottommost annular reservoir 539. And, for the purposes of illustration and explanation, the height of each annular reservoir is the same and is equal to the height of each central reservoir.

In response to the illustrated tilt of the PTO, the central reservoirs 548-552 of the PTO's five inner levels are lifted and/or elevated relative to the annular reservoir segments 557-562 of the PTO's six outer levels (400-405 in FIG. 41). Because the angle 537 of the tilt exceeds the angle 563 of each central ramp originating at each respective elevated central reservoir 548-552, water held, deposited, and/or trapped, within each elevated central reservoir 548-552 flows, e.g., 564, “up” (which, with respect to gravity is “down” due to the tilt 537) each central reservoir's respective central ramp, and over each central ramp's respective waterfall edge, e.g., 565, thereby falling down and into the respective annular reservoir segment 558-562 immediately adjacent to, and “above” (which, with respect to the tilt 537 is actually “below”), each respective inner layer's elevated central reservoir 548-552.

Water trapped, deposited, and/or held, within the annular reservoir segment 562 of the uppermost outer layer (405 in FIG. 41) flows 566 into and through a turbine reservoir and then into and/or through a water turbine 567 that is operably connected to a generator that generates electrical power in response to the flow. The water discharged from the water turbine flows 568 out through an effluent pipe.

In response to the illustrated tilt of the PTO, at least one inlet aperture is at least partially submerged, and water flows 569 into the at least partially submerged annular reservoir segment 557.

In one embodiment, the water discharged 568 from the effluent pipe flows back into the body of water on which the PTO's embodiment (not shown) floats, and water from the body of water enters 569 annular reservoir segment 557. In another embodiment, the water discharged 568 from the effluent pipe flows into a reservoir outside the PTO, and water from that reservoir enters 569 annular reservoir segment 557.

If the magnitude of the tilt, the duration the tilt, or a combination of both, is sufficient, then water flowing from the elevated annular reservoir segments, e.g., 539, will flow into a respective central reservoir, e.g., 548, and at least a portion of that water will continue flowing from that respective central reservoir into the lowered respective annular reservoir segment, e.g., 558.

In other words, in response to a minimally sufficient tilt, water will flow from an annular reservoir segment into a corresponding central reservoir, or, water will flow from a central reservoir into a corresponding annular reservoir segment, such that the water circulating within the PTO will tend to be elevated by one-half “step” (if a “step” is regarded as the height of each annular reservoir segment and each central reservoir) in response to the tilt. However, in response to an abundantly sufficient tilt, water will flow from an annular reservoir segment to an approximately opposing annular reservoir segment (by means of an intermediate central reservoir), such that the water circulating within the PTO will tend to be elevated by full “step” in response to the tilt.

FIG. 56 shows a side view of a schematic/functional illustration of the same power takeoff (PTO) illustrated in FIGS. 41-54, and the same schematic illustrated in FIG. 55. However, in FIG. 56, the direction of the tilt 570 is approximately opposite that of the tilt 537 illustrated in FIG. 55.

The base and/or bottom surface 536 of the PTO corresponds to the bottom of the bottommost outer layer (400 in FIG. 41) of the PTO. When the PTO, and the floating embodiment to which it is attached, are tilted 570, in response to a wave passing across the surface of the body of water on which the embodiment (not shown) to which the PTO is attached, the orientation of the PTO is altered and rotated through an angle 570 from the horizontal (e.g., from the resting surface of the body of water) 538.

In response to the illustrated tilt 570 of the PTO, the annular reservoir segments 557-562 of the PTO's six outer levels (400-405 in FIG. 41) are lifted and/or elevated relative to the central reservoirs 548-552. Because the angle 570 of the tilt exceeds the angle 571 of each annular ramp originating at each respective elevated annular reservoir segment 557-561, water held, deposited, and/or trapped, within each elevated annular segment 557-561 flows, e.g., 572, “up” (which, with respect to gravity is “down” due to the tilt 570) each segment's respective annular ramp, and over each annular ramp's respective waterfall edge, e.g., 573, thereby falling down and into the respective central reservoir 548-552 immediately adjacent to, and “above” (which, with respect to the tilt 570 is actually “below”), each respective outer layer's elevated annular reservoir segment 557-561.

In response to the illustrated tilt of the PTO, the central reservoirs 548-552 of the PTO's five inner levels are lifted and/or elevated relative to the annular reservoir segments 539-544 of the PTO's six outer levels (400-405 in FIG. 41). Because the angle 570 of the tilt exceeds the angle 574 of each central ramp originating at each respective elevated central reservoir 548-552, water held, deposited, and/or trapped, within each elevated central reservoir 548-552 flows, e.g., 575, “up” (which, with respect to gravity is “down” due to the tilt 570) each central reservoir's respective central ramp, and over each central ramp's respective waterfall edge, e.g., 576, thereby falling down and into the respective annular reservoir segment 540-544 immediately adjacent to, and “above” (which, with respect to the tilt 570 is actually “below”), each respective inner layer's elevated central reservoir 548-552.

Water trapped, deposited, and/or held, within the annular reservoir segment 544 of the uppermost outer layer (405 in FIG. 41) flows 577 into and through a turbine reservoir and then into and/or through a water turbine 578 that is operably connected to a generator that generates electrical power in response to the flow. The water discharged from the water turbine flows 579 out through an effluent pipe.

In response to the illustrated tilt of the PTO, at least one inlet aperture is at least partially submerged, and water flows 580 into the at least partially submerged annular reservoir segment 539.

In one embodiment, the water discharged 579 from the effluent pipe flows back into the body of water on which the PTO's embodiment (not shown) floats, and water from the body of water enters 580 annular reservoir segment 539. In another embodiment, the water discharged 579 from the effluent pipe flows into a reservoir outside the PTO, and water from that reservoir enters 580 annular reservoir segment 539.

If an embodiment similar to the one illustrated schematically in FIGS. 55 and 56 draws in water from the body of water on which the embodiment to which the PTO is attached, then in response to tilt 570 water would not flow 569 into annular reservoir segment 557 in response to that tilt. However, if an embodiment similar to the one illustrated schematically in FIGS. 55 and 53 draws in water from a reservoir outside and/or around the base of the PTO, then in response to tilt 570 water might still flow 569 into annular reservoir segment 557 from that reservoir.

If the magnitude of the tilt, the duration the tilt, or a combination of both, is sufficient, then water flowing from the elevated annular reservoir segments, e.g., 561, will flow into a respective central reservoir, e.g., 552, and at least a portion of that water will continue flowing from that respective central reservoir 552 into the lowered respective annular reservoir segment, e.g., 544.

In other words, in response to a minimally sufficient tilt, water will flow from an annular reservoir segment into a corresponding central reservoir, or, water will flow from a central reservoir into a corresponding annular reservoir segment, such that the water circulating within the PTO will tend to be elevated by one-half “step” (if a “step” is regarded as the height of each annular reservoir segment and each central reservoir) in response to the tilt. However, in response to an abundantly sufficient tilt, water will flow from an annular reservoir segment to an approximately opposing annular reservoir segment (by means of an intermediate central reservoir), such that the water circulating within the PTO will tend to be elevated by full “step” in response to the tilt.

FIG. 57 shows a perspective side view of an embodiment of the present disclosure that incorporates the power takeoff (PTO) illustrated in FIGS. 41-54, and discussed in relation to FIGS. 55 and 56. The embodiment's PTO 581 is positioned at the center of a buoy 582, flotation module, buoyant structure, vessel, and/or float, and the embodiment floats adjacent to an upper surface 583 of a body of water over which waves tend to pass.

FIG. 58 shows a top-down view of the same embodiment of the present disclosure that is illustrated in FIG. 57.

A water reservoir 584 is positioned between the outer walls of the embodiment's power takeoff (PTO) 581 and the inner walls of a cavity, depression, enclosure, and/or hole, within the embodiment's buoy 582. Water flows into the PTO through the PTO's inlet apertures, e.g., 406, and is elevated through outer and inner layers of the PTO in response and/or as a consequence of wave-induced tilting. Water that has been raised to the highest annular reservoir within the PTO then flows into and through water turbines positioned below, and operably connected to, generators, e.g., 415, that generate electrical power in response to the water flowing through them. The water discharged from the water turbines flows back into the water reservoir 584 from which it was originally drawn, obtained, and/or taken.

The water (or other fluid) that flows through the PTO is repeatedly deposited into the embodiment's water reservoir 584 and therefrom repeatedly recycled and/or recirculated through the PTO.

FIG. 59 shows a side perspective sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 57 and 58 wherein the vertical section plane is specified in FIG. 58 and the section is taken across line 59-59. Water at the highest annular reservoir of the embodiment's power takeoff (PTO) 581 flows through a turbine pipe, e.g., 411, and therethrough a water turbine, e.g., 459, that is operably connected to a generator, e.g., 414. After its discharge from the water turbine's effluent tube, e.g., at mouth 460, water is deposited into, accumulates and is stored within, the embodiment's water reservoir 584, until it again enters an inlet aperture, e.g., 406, and is again lifted within the PTO, and is again discharged from a water turbine's effluent tube.

FIG. 60 shows a perspective side view of a power takeoff (PTO) characteristic of an embodiment of the present disclosure. The full embodiment of which the illustrated PTO is a part includes a flotation platform (not shown) to which the illustrated PTO is attached and the embodiment floats adjacent to an upper surface of a body of water over which waves pass.

The PTO 600 has a side cylindrically-shaped outer wall 601, a flat upper wall 602, and a flat bottom wall (not visible). Thus the PTO is sealed, enclosed, and/or contained within, an outer shell 601/602.

Wave-induced tilting of the illustrated PTO results in water (or another fluid) flowing from a reservoir inside the PTO up a spiral ramp (not visible) until it achieves a maximal elevation, height, and/or head pressure, relative to the reservoir from which it originated. The PTO's spiral ramp is partially partitioned by tangentially-oriented vertical walls (not visible) that tend to prevent the backflow of water. Water elevated to a height near the maximum possible height of the PTO's spiral water-lifting ramp falls into a turbine reservoir (not visible). And, water within the turbine reservoir flows through, energizes, and causes to rotate, a water turbine (not visible) which is operably connected to a generator 603 by a shaft 604, thereby causing the generator to generate electrical power.

FIG. 61 shows a side view of the same power takeoff (PTO) illustrated in FIG. 60. The PTO 600 has a solid bottom wall 605.

FIG. 62 shows a top-down view of the same power takeoff (PTO) illustrated in FIGS. 60 and 61.

FIG. 63 shows a side sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 60-62 wherein the vertical section plane is specified in FIG. 62 and the section is taken across line 63-63.

Inside the PTO's 600 canister 601/602/605 is a continuous spiral ramp 606. When the PTO tilts, e.g., in response to wave motion buffeting the embodiment of which the PTO is a component, then water flows in an approximately circular motion and/or path and flows up the spiral, travelling from the spiral's bottom (near the bottom 605) to the top (near the top 607 of the PTO's central cylindrical tube 608). When water reaches the top of the spiral, it tends to spill over the edge of the upper mouth 607 of the PTO's central cylindrical tube 608, thereby tending to create a reservoir of water within that tube, a “turbine reservoir”. Water accumulated within the PTO's turbine reservoir 608 flows down and into a constricted portion 609 and/or throat of the tube. Water flowing through the central tube's throat 609 flows through, energizes, and causes to rotate, a water turbine 610 positioned therein. Rotations of the water turbine 610 are communicated to the turbine's shaft 604 which is operably connected to a generator 603. Thus, water flowing down through the PTO's central cylindrical tube 608 causes generator 603 to generate electrical power.

A portion of the energy imparted by waves to the embodiment of which the PTO is a part is captured as an increase in the gravitational potential energy of water within the PTO as water is incrementally lifted through its motion about the PTO's spiral ramp 606. At the top of the PTO's spiral ramp, the raised water falls into the turbine reservoir 608, vessel, reservoir, and/or pool, after which its gravitational potential energy is manifested as head pressure that drives the water through water turbine 610 thereby converting the gravitational potential energy of the water in the turbine reservoir into electrical power.

Water discharged from the water turbine 610 flows into the base 611 of the PTO's central cylindrical tube 608 where apertures, e.g., 612, allow the discharged turbine water to flow back into the base of the spiral ramp, and thereby flow up the spiral ramp again as wave-induced tilting of the PTO, and the embodiment of which it is a part, incrementally lift the water higher and higher.

A set of vertical walls, e.g., 613, tend to trap water during those moments when tilting is not favorable to its further flow up the spiral ramp, and until favorable tilting resumes. In addition to vertical walls oriented approximately tangentially to the PTO's central cylindrical tube 608, the spiraling surface of which the spiral ramp 606 is comprised is lower at its outer edge than at the edge proximate to the central tube.

A vertical section through the longitudinal axis about which the spiral ramp is wound (as illustrated in FIG. 63) shows ramps for which the vertical ramp section is not normal to that longitudinal axis. Instead, the vertical ramp sections are oriented to the spiral ramps longitudinal axis at an angle away from normal such that the distal and/or outer end of each ramp section is closer to the PTO's base 605 than is the point at which each ramp section is connected to the PTO's central cylindrical tube 608. In the illustrated PTO the downward angle of each ramp is approximately 3 degrees relative to a normal from the vertical longitudinal axis about which the spiral ramp is wound.

The scope of the present invention includes PTOs with spiral ramps wherein a vertical section through the longitudinal axis about which the spiral ramp is wound would be characterized by ramps for which the vertical ramp section is normal to that longitudinal axis.

The scope of the present invention includes PTOs with spiral ramps characterized by any spiral ramp angle.

FIG. 64 shows the same side sectional view illustrated in FIG. 63 from a perspective view. If viewed from the top, water flows through the PTO in a counterclockwise direction. So, in response to a favorable tilting of the PTO, water flowing up the PTO's spiral ramp 606 will impact diverting wall 613 and thereby be directed further up the ramp. In the absence of such diverting walls, water would still flow up the spiral ramp 606, but would then tend to flow back down when the favorable tilt causing its flow changed direction or stopped. Theoretically, a tilt manifested as a precession of the PTO about a vertical axis normal to the resting surface of the body of water on which the PTO, and the embodiment of which it is a part, float could cause water to flow up the spiral ramp 606, and to be deposited within the turbine reservoir 608, without any diverting walls to prevent backflow.

FIG. 65 shows a top-down sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 60-64 wherein the horizontal section plane is specified in FIG. 60 and the section is taken across line 65-65.

The spiral ramp ascends in a counterclockwise direction with respect to the orientation of the illustration in FIG. 65. The spiral ramp 606 ends at tangential diverting wall 615. Upward spiraling water that encounters diverting wall 615 is further obstructed by a radial wall 616. The eight tangential diverting walls 613, 615, and 617-622, extend from the bottom wall (605 in FIG. 61) of the PTO up to the top wall (602 in FIG. 61). However, radial wall 616 extends only from the uppermost end of the spiral to the top wall.

Water ascending the spiral ramp 606 must flow in a circular fashion between the innermost ends of the of the diverting walls and the outer wall of the central cylindrical tube 607.

In response to a favorable tilt, e.g., of direction 623, water flows 624 out from under the uppermost end 625 and/or level of the PTO's spiral ramp in the gap between the inner vertical edge of diverting wall 615 and the central tube 607. Because of the water's direction of flow (e.g., approximately parallel to the direction 623 of the tilt), and because the outer edges and/or ends of the spiral ramps are lower than the inner edges and/or ends, the water flowing in response to a favorable tilt of direction 623, will be diverted into spiral reservoir 626 where the downward radial angle of the ramp and the opposing diverting walls 617 and 613 will effectively if not perfectly trap the water until another tilt of favorable direction moves the water further up the spiral.

In response to a favorable tilt, e.g., of direction 627, water trapped within spiral reservoir 628 flows 629 out of the reservoir, around the central tube 607, and into spiral reservoir 630. Another favorable tilt, e.g. in the direction of 623, causes the water trapped within spiral reservoir 630 to flow 631 against the diverting wall 622, and in a direction tangential to the central tube 607, until the flowing water is obstructed by radial wall 616 which causes it to spill over and into the central cylindrical tube and turbine reservoir 608. Water within the turbine reservoir 608 then flows down to, and through, the water turbine 610 positioned within the constricted throat of the central tube 608, thereby causing the operably connected generator (603 in FIG. 61) to generate electrical power.

FIG. 66 shows the same top-down sectional view illustrated in FIG. 65 from a perspective view.

FIG. 67 shows a perspective side view of the same embodiment of the present disclosure that is illustrated in FIGS. 60-66. In FIG. 67 the cylindrical side wall (601 in FIG. 60) and the top wall (602 in FIG. 60) have been removed and/or omitted for the purpose of illustration. Except for the removal of those walls, the configuration of the power takeoff (PTO) in FIG. 67 is identical to the one illustrated in FIG. 60.

Water discharged from the PTO's water turbine and/or turbine reservoir flows out and into the lowest level(s) of the PTO's spiral ramp 606, i.e., those portions of the ramp adjacent or near to the PTO's bottom wall 605.

As water is incrementally lifted up the spiral ramp through wave-induced tilting of the PTO, the water eventually flows out of aperture 625 and will thereafter either spontaneously spill over the ever shortening upper lip of the mouth at the top of the turbine reservoir 608, or it will be directed into that mouth by radial wall 616 if it completes another rotation about the spiral after emerging from aperture 625.

FIG. 68 shows a perspective side view of an embodiment of the present disclosure that incorporates the power takeoff (PTO) illustrated in FIGS. 60-67. The embodiment's PTO 600 is positioned at the center of a buoy 632, flotation module, buoyant structure, vessel, and/or float, and the embodiment floats adjacent to an upper surface 633 of a body of water over which waves tend to pass.

FIG. 69 shows a top-down view of the same embodiment of the present disclosure that is illustrated in FIG. 68. Between the power takeoff (PTO) 600 and the enclosing buoy 632 is a gap which exists primarily for the purpose of illustration. An embodiment similar to the one illustrated in FIG. 69 has no such gap.

FIG. 70 shows a side perspective sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 68 and 69 wherein the vertical section plane is specified in FIG. 69 and the section is taken across line 70-70. Upon reaching the uppermost level of the spiral ramp of the PTO 600, water falls into the turbine reservoir within the PTO's central tube and thereafter flows down and through a water turbine therein. After being discharged by the water turbine, water flows down and back onto the lowest level(s) of the PTO's spiral ramp, after which it will again ascend to the top of the turbine reservoir—repeating this cycle endlessly.

In an embodiment similar to the one illustrated in FIGS. 68-70, a void, chamber, vessel, enclosure, and/or tank, of water ballast is positioned in a bottom portion of the embodiment's buoy 632.

FIG. 71 shows a perspective side view of an embodiment 650 of the present disclosure that incorporates a plurality of the type of power takeoff (PTO) disclosed herein. The embodiment floats adjacent to an upper surface 651 of a body of water over which waves tend to pass. Each hexagonal columnar structure, e.g., 652-654, is a PTO of one of the types disclosed herein. The embodiment may incorporate a variety of different PTOs, PTOs of different sizes, PTOs of different rated electrical power levels, PTOs fabricated of different materials, PTOs converting the energy of waves into electrical power by means of different operating fluids, PTOs which draw water from the body of water 651 and PTOs that recycle an operating fluid within a closed system.

The illustrated multi-PTO embodiment 650 incorporates an energy-consuming processing module 655, system, factory, mechanism, and/or device, and therein or therethrough utilizes at least a portion of the electrical power that it produces to process a material, extract a material, execute computations, generate an energy-storing chemical, and/or recharge an energy-storing material, system, battery, capacitor, or other energy-storage system.

The embodiment includes an input chamber 656, vessel, enclosure, and/or structure, within which raw materials, feedstock, ingredients, and/or other substances, are stored until needed by the processing module 655, after which they are transmitted, communicated, delivered, transferred, and/or provided, to the processing module.

The embodiment includes two output chambers 657 and 658, vessels, enclosures, and/or structures, within which are stored processed products produced, at least in part, by the processing module 655.

In one embodiment 650, at least one of the output vessels stores liquefied hydrogen, and the input vessel includes replacement electrolyzers to facilitate the generation of hydrogen from seawater.

In another embodiment 650, at least one of the output vessels stores liquefied ammonia, and the input vessel includes devices that separate atmospheric nitrogen from the air.

In another embodiment 650, at least one of the output vessels includes memory storage devices that store computational problems received by the embodiment from radio transmissions (or other sources), and/or the results of computations performed by the computational circuits within the processing module until the time that those results, or a portion thereof, can be transmitted to a remote computer by radio transmissions (or by other communications channels and/or methods).

In another embodiment 650, at least one of the PTOs, e.g., 652, does not convert the gravitational potential energy of the water it lifts into electrical energy. Instead it uses that potential energy to desalinate water.

In another embodiment 650, at least one of the PTOs, e.g., 652, does not convert the gravitational potential energy of the water it lifts into electrical energy. Instead it uses that potential energy to extract a mineral from the seawater on which the embodiment floats.

FIG. 72 shows a perspective side view of an embodiment 700 of the present disclosure. A compartment, enclosure, and/or chamber 701, contains a wave-energized diode pump similar to the one illustrated in FIGS. 15-19 which utilizes reservoirs connected to ramps, and/or inclined channels, over and/or through which, in response to wave-induced tilting of the diode pump, water flows back and forth between opposing reservoirs at ever increasing relative heights thereby progressively and/or incrementally gaining gravitational potential energy.

Water that has flowed through the diode pump and reached the top of the pump is thereafter directed into a channel (not visible) containing a water turbine (not visible) rotatably connected to a generator 702. The water flowing down through the turbine channel engages and/or energizes the water turbine thereby imparting rotational kinetic energy and/or rotational torque to the generator 702 and thereby generating electrical power.

The illustrated embodiment 700 is sealed and the water contained therein is lifted by wave action through the diode pump to a maximal height after which it flows through the embodiment's water turbine, thereby generating electrical power. After flowing through the water turbine, the water within the illustrated embodiment flows back into the diode pump and is again, and repeatedly, raised to the top of the pump in response to continued wave action.

The diode pump 701 of the illustrated embodiment is rigidly connected to a plurality of diode hinge elements, e.g., 703, which rotate about a shaft 704 and/or axle that rotatably connects the diode hinge elements, e.g., 703, to a corresponding and/or complementary plurality of base hinge elements, e.g., 705. The base hinge elements, e.g., 705, are rigidly attached to a base 706 and/or platform that is typically attached to, and/or resting upon, the ground, e.g., the seafloor, at the base of the body of water in which the embodiment 700 is typically deployed.

The illustrated embodiment 700 is a closed system and recycles and/or recirculates the water that its diode pump raises. Another embodiment similar to the one illustrated in FIG. 72 receives water from the body of water in which the embodiment is deployed, e.g., from the sea, and after that water has been raised and subsequently directed to flow through the embodiment's water turbine, is returned to that body of water, e.g., to the sea. Another embodiment similar to the one illustrated in FIG. 72 also receives water from the body of water in which it is deployed utilizes the gravitational potential energy of the water raised by the embodiment's diode pump in order to generate pressurized water that is subsequently desalinated, e.g., by a membrane assembly within the embodiment. And another embodiment similar to the one illustrated in FIG. 72 which receives water from the body of water in which it is deployed utilizes the gravitational potential energy of the water raised by the embodiment's diode pump in order to extract minerals from the water thereby pressurized.

An embodiment similar to the one illustrated in FIG. 72 also contains an apparatus that performs useful work using a portion of the electrical power generated by the embodiment's generator 702. One such embodiment contains computing devices that perform computational tasks it receives from a remote, e.g., a shore-based, computer and/or computing network, e.g., via a subsea cable or via satellite, and which return computational results to a remote computer and/or computing network, e.g., via a subsea cable or via satellite.

An embodiment similar to the one illustrated in FIG. 72 utilizes a working fluid of ammonia instead of water.

Because the diode pump 701 within the embodiment of FIG. 72 contains a working fluid and air (or other gas, e.g., nitrogen or ammonia), the embodiment tends to be buoyant. A buoyant embodiment similar to the one illustrated in FIG. 72 is connected to the ground, e.g., the seafloor, at the base of the body of water in which the embodiment 700 is deployed, by a plurality of flexible connectors, e.g., chains, ropes, steel cables, linkages, cables comprised of carbon fiber, etc., one end of which are connected to a bottom surface and/or portion of the diode pump 701, and the other end of which are connected to a base (such as 706), a platform, a plurality of pylons, and/or other connectors to the ground. The chains tend to keep the buoyant embodiment connected to the ground, e.g. to the seafloor, while allowing the diode pump 701 to tilt and/or rock back and forth in response to wave action.

The generator 702 of the illustrated embodiment 700 is positioned outside and above the enclosure 701 housing the embodiment's diode pump. However, the scope of the disclosure includes any number of generators, any type(s) of generator(s), any position of a generator within the embodiment, e.g., within the diode pump housing 701, any type, shape, design, and/or position of enclosure about the generator.

FIG. 73 shows a front side view of the same embodiment 700 of the present disclosure that is illustrated in FIG. 72.

The illustrated embodiment 700 is deployed within a body of water 707 and rests on the ground 708, e.g. the seafloor, beneath the body of water 707.

The diode pump 701 of the embodiment 700 is encased and/or enclosed within outer walls, including a topmost wall 709, a bottommost wall 710, and side walls 701. The generator 702 is rotatably connected to the water turbine (not visible) by a shaft 711.

FIG. 74 shows a right-side view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72 and 73.

At the back of the diode pump enclosure 701 is an upper receiving chamber 712 into which water flows after reaching and being deposited into the upper most reservoir of the diode pump. Water within the upper receiving chamber 712 flows into turbine tube 713 in which a water turbine (not visible) is positioned. Water flows down through the turbine tube 713, and through the water turbine therein, thereby imparting energy to the water turbine and therethrough to the rotatably connected generator 702, thereby generating electrical power. After flowing through the water turbine, water down through the turbine tube 713 flows into the lower receiving chamber 714 and then back into the lower most reservoir of the diode pump.

An embodiment is typically deployed in an orientation that places its hinge axle 704 parallel to the dominant and/or typical wave front, and/or normal to the dominant and/or typical wave direction. In such an orientation, the diode pump will tend to tilt with a maximal amplitude and/or degree and will therefore tend to operate with maximal efficiency, i.e., it will tend to lift water up through the diode at a maximal rate of flow.

FIG. 75 shows a back-side view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72-74.

FIG. 76 shows a top-down view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72-75. The diode pump enclosure 701 has an upper enclosure wall 709.

FIG. 77 shows a side view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72-76. In the illustration of FIG. 77, the embodiment's upper portion (i.e., the diode hinge elements, e.g., 703, the pump diode 701, the turbine manifold 712-714, and the generator 702) responds to the passage of a wave across the surface 707 of the body of water in which it is deployed, by swaying, tilting, and/or rotating 715, about its rotational shaft 704 from an initial position and/or orientation at 700L, to a new position and/or orientation at 700R (i.e. the wave is traveling from left to right with respect to the illustration). As it rotates, water within the diode pump 701 flows from a plurality of leftmost reservoirs (not visible), up a plurality of ramps and/or inclined channels (not visible), and into corresponding and/or respective rightmost reservoirs (not visible).

In response to the wave's return stroke (i.e., when the direction of the wave's surge reverses), the embodiment's upper portion will respond by swaying, tilting, and/or rotating 715, about its rotational shaft 704 from an initial position and/or orientation at 700R, to a new position and/or orientation at 700L. And, the water that was lifted as a consequence of its left-to-right flow up the right-ascending ramps of the embodiment's diode pump 701, will be further lifted as a consequence of a right-to-left flow up the left-ascending ramps of the embodiment's diode pump.

With the passage of each wave of sufficient amplitude and period, the water within the embodiment's diode pump will be raised. And, with the passage of each wave of sufficient amplitude and period, a portion of the water within the diode pump will flow into the embodiment's upper receiving chamber 712, and therethrough into the embodiment's turbine tube 713, therein flowing through, and imparting energy to, the water turbine positioned therein.

FIG. 78 shows a side perspective view of a representative portion of the type of back-and-forth ramp structure of which the diode pump of the embodiment of the present disclosure that is illustrated in FIGS. 72-77 is comprised.

The actual diode pump of the embodiment illustrated in FIGS. 72-77 is surrounded by an enclosure (701 in FIG. 72) that encloses the water that is contained within the reservoirs of the diode, and that flows up the ramps of the diode in response to wave action. Moreover, vertical walls and/or barriers separate and/or isolate the individual ramps from one another within the actual diode pump. Because of the vertical side walls separating each ramp from its neighbors, and the ramp above, each ramp is a channel and/or pipe through which water may flow from an originating reservoir to a receiving reservoir, wherein the receiving reservoir is at a greater height above, and/or distance from, the lowest reservoir, e.g., 716.

The illustration of FIG. 78 omits the vertical walls that constrain the movement of the water within the embodiment's actual diode pump in order to better illustrate the path followed by water as it flows upward within the diode in response to wave action.

When a wave tilts the diode pump to the left (with respect to the illustration in FIG. 78) by a sufficient degree, amplitude, and/or magnitude, and for a sufficient duration and/or period, then water held within an originating reservoir 716 (which, in the absence of the nominal vertical walls is illustrated as the base, bottom wall, and/or floor, of that reservoir) tends to flow 717 through channel 718 (which, in the absence of the nominal vertical walls is illustrated as the base, bottom wall, and/or floor, of that ramp) and to thereafter fall over the “waterfall edge” 719 at the distal end of the ramp 718, and thereby fall into, and become trapped and/or entrained within receiving reservoir 720.

A “waterfall edge” is an edge of an upper surface of a ramp that is raised relative to an adjacent lower surface, reservoir, chamber, and/or void, such that a fluid flowing from the upper surface of the ramp, and over the waterfall edge, will tend to fall and/or flow downward into the receiving reservoir, and/or onto the lower surface. The waterfall edge at the end of a ramp, e.g., 719, tends to cause water flowing, e.g., 717, toward the end and/or edge of the ramp to “fall over” the ramp's edge 719 and fall into, and become trapped within, a receiving reservoir, e.g., 720.

When a wave, and/or wave surge, with an approximately opposite direction tilts the diode pump to the right (with respect to the illustration in FIG. 78) by a sufficient degree, amplitude, and/or magnitude, and for a sufficient duration and/or period, then the receiving reservoir 720 becomes the originating reservoir, and water held within the new originating reservoir 720 (which, in the absence of the nominal vertical walls is illustrated as the base, bottom wall, and/or floor, of that reservoir) tends to flow 721 through channel 722 (which, in the absence of the nominal vertical walls is illustrated as the base, bottom wall, and/or floor, of that ramp) and to thereafter fall over the “waterfall edge” 723 at the distal end of the ramp 722, and thereby fall into, and become trapped and/or entrained within receiving reservoir 724.

This pattern of tilt-induced water flow from originating reservoirs, e.g., 720, up and through ramps, and/or inclined channels, e.g., 722, over waterfall edges, e.g., 723, and into receiving reservoirs, e.g., 724, is repeated with each wave-induced tilt reversal of sufficient magnitude and period. Water that originates within the lowermost reservoir 716 eventually, incrementally, and progressively, rises from reservoir to reservoir, with each reservoir being positioned at a greater height above, and/or distance from, the lowermost reservoir 716, until it is deposited in an uppermost reservoir 725 after which the water will possess a substantial amount of gravitational potential energy. The raised water, held in the uppermost reservoir 725, may then be directed to flow through a water turbine that converts a portion of its gravitational potential energy into mechanical energy that may be used to energize a generator and generate electrical power. The raised water may be used to create a pressurized flow of water through desalination membranes thereby extracting relatively fresh water from relatively saline water, e.g., from seawater. The raised water may also be used to create a pressurized flow of water through mineral-extraction membranes, mats, and/or other porous structures, thereby extracting minerals from mineral-rich water, e.g., from seawater.

The example diode flow structure illustrated in FIG. 78 is comprised of 11 reservoirs on the left and 12 reservoirs on the right with one ramp and/or inclined channel originating from all but the uppermost reservoir 725 on the right. In the embodiment (700 in FIG. 72), the diode pump (701 in FIG. 72) is comprised of 30 reservoirs on the leading side (the side closest to approaching waves, and/or, with respect to a typical deployment, the side furthest from the shoreline) and 31 reservoirs on the trailing and/or opposite side. Each reservoir of the embodiment 700 spans the full width of the diode pump.

Each reservoir in the sample diode illustrated in FIG. 78 (other than the uppermost reservoir) is the originating reservoir for a single ramp. And, each reservoir in the sample diode illustrated in FIG. 78 (other than the lowermost reservoir) is the receiving reservoir for a single ramp. However, in the embodiment (700 in FIG. 72), each reservoir (other than the uppermost reservoir) is the originating reservoir for 12 ramps. And, each reservoir in the sample diode illustrated in FIG. 78 (other than the lowermost reservoir) is the receiving reservoir for 12 ramps.

FIG. 79 shows a side sectional view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72-77 wherein the vertical section plane is specified in FIG. 76 and the section is taken across line 79-79.

Effluent from the water turbine 726 enters the lower receiving chamber 714 and then flows 715 into the lowermost reservoir 727 of the diode pump 701. In response to a sufficient and favorable wave-induced tilt of the diode 701, water in the lowermost reservoir 727 of the diode pump tends to flow “up” (which during a sufficient and favorable wave-induced tilt of the diode is actually “down” with respect to gravity) the ramp and/or inclined channel 728, over the waterfall edge 729 of the ramp 728, and down and into receiving reservoir 730.

Because of the vertical wall 731 that separates the reservoirs and ramps visible within the illustration of FIG. 79, the only reservoirs and ramps visible in the figure are those which lift water and/or cause water to flow up a ramp in response to a rightward tilting 732 of the diode 701. With respect to the reservoirs and ramps visible in the illustration of FIG. 79, each reservoir, e.g., 727, on the left side of the diode pump (with the exception of the uppermost reservoir 733) is an originating reservoir, each reservoir, e.g., 730, on the right side of the diode pump is a receiving reservoir, and each ramp is inclined so as to raise water flowing from left to right, i.e. in response to a rightward tilting 732 of the diode 701.

The reservoirs and ramps adjacent to the illustrated vertical assortment of reservoirs and ramps, i.e., the reservoirs and ramps in front of the section plane as well as those behind the vertical wall 731, are of an opposite arrangement. The reservoirs on the left and right are present across the entire width of the diode pump 701. However, the reservoirs and ramps adjacent to the illustrated vertical assortment of reservoirs and ramps differ from those illustrated in FIG. 79 in that with respect to those unseen adjacent reservoirs and ramps (e.g., those visible in FIG. 80), the reservoirs on the left are receiving reservoirs, the reservoirs on the right are originating reservoirs, and the ramps are inclined so as to raise water flowing from right to left, i.e. in response to a leftward tilting of the diode 701.

As a consequence of a series of sufficient and favorable wave-induced tilts of the diode, in alternating left and right directions of tilt, water ascends through the diode pump 701 in the manner explained in relation to the illustration and description associated with FIG. 78. Water deposited into receiving reservoir 734 will, in response to a sufficient and favorable wave-induced tilt of the diode in a leftward direction flow up and into receiving reservoir 733 after which it will tend to flow 735 out and into the upper receiving chamber 712. Slanted peripheral walls, e.g., 736, direct water so deposited into the upper receiving chamber 712 into the upper mouth, end, and/or aperture, of the turbine tube 713 wherein it eventually flows down and through water turbine 726, thereby imparting mechanical and/or rotational power to shaft 711 which is rigidly attached and/or connected to water turbine 726. And, the rotation of shaft 711 causes the operably connected generator 702 to generate electrical power.

After passing through the water turbine, water flowing down and through turbine tube 713 (i.e., the turbine's effluent) flows into the lower receiving chamber 714, and thereafter into the lowermost reservoir 727 of the diode pump 701. And, the cycle repeats . . . .

FIG. 80 shows a side sectional view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72-77 and 79 wherein the vertical section plane is specified in FIG. 76 and the section is taken across line 80-80.

The diode pump 701 of the embodiment 700 contains opposing sets of reservoirs that are interconnected by ramps and/or inclined channels. In the embodiment illustrated in FIGS. 72-77 and 79, the ramps and/or channels directly above and/or below one another, i.e., in a vertical segment of the diode, are characterized by a specific, particular, and consistent, angle of inclination. The cross-sectional view illustrated in FIG. 79 illustrates one such vertical diode segment wherein the ramps are characterized by a particular angle of inclination that ascends from the “back” of the diode (i.e., the side nearest the turbine 726) to the “front” (i.e., the side furthest from the diode). The cross-sectional view illustrated in FIG. 80 illustrates another such vertical diode segment wherein the ramps are characterized by a second particular angle of inclination that ascends from the “front” (i.e., the side furthest from the diode) of the diode to the “back” (i.e., the side nearest the turbine 726).

The diode pump 701 of the embodiment is comprised of 12 vertical diode segments in which the ramps are inclined such that they ascend from the “back” of the diode to the “front” (e.g., as illustrated in FIG. 79), and 12 vertical diode segments in which the ramps are inclined such that they ascend from the “front” of the diode to the “back” (e.g., as illustrated in FIG. 80). The back-to-front ascending vertical diode segments are interleaved with the front-to-back vertical diode segments. Each vertical diode segment is separated from its adjacent neighbors by vertical walls (e.g., 731 in FIG. 79).

Whereas water flows from the back of the diode to the front within the vertical diode segment illustrated in FIG. 79 (i.e., when the diode is appropriately tilted, e.g., 732 in FIG. 79), water flows from the front of the diode to the back within the vertical diode segment illustrated in FIG. 80. In the embodiment's diode pump 701, 12 pairs of complementary vertical diode segments (i.e., complementary in that one lifts water in response to tilts in one direction, and the other lifts water in response to tilts in an opposing direction) cooperate to raise water from the embodiment's lowest reservoir 727 to its highest reservoir 733 whereafter the water flows into the embodiment's turbine manifold 712-714 and therein flows through the embodiment's water turbine 726 thereby imparting power to the operably connected generator 702 and causing that generator to produce electrical power.

In response to a wave-induced tilt 737 of the embodiment's diode pump 701, that is of favorable direction and sufficient magnitude and period, water within a leftmost originating reservoir, e.g., 730 and 734, flows across a nominally upwardly-inclined ramp, and/or channel, e.g., 737 and 738, that directs the water to a receiving reservoir, e.g., 733 and 740, that is higher than, and/or further from, the bottom of the embodiment and/or from the ground, e.g., seafloor, on which the embodiment rests and/or is attached. Because of the wave-induced tilt 737 of the embodiment's diode pump 701 the nominally upwardly-inclined ramps, and/or channels, of the illustrated vertical diode segment are, with respect to the pull of gravity, actually downwardly-inclined.

Water flowing from reservoir 734, through channel 739, and into reservoir 733, thereafter flows 735 into the upper receiving chamber 712, and thereafter into the turbine tube 713, through the water turbine 726, into the lower receiving chamber 714, and it then flows 715 back into the bottommost reservoir 727 from which it will again be pumped to the top of the diode and back through the turbine 726 again and again.

Please note that the arrow 732 of FIG. 79 illustrates the pump diode 701 tilting and/or rotating toward its front and/or away from its turbine 726, whereas the arrow 737 of FIG. 80 illustrates the pump diode 701 tilting and/or rotating toward its turbine 726 and/or away from its front.

FIG. 81 shows a top-down sectional view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72-77 and 79-80 wherein the horizontal section plane is specified in FIG. 74 and the section is taken across line 81-81.

In response to a favorable tilt (e.g., 732 in FIG. 79) toward the front of the embodiment's diode pump, i.e., away from the turbine (726 in FIG. 79), water flows, e.g., 741, from the reservoir immediately below, e.g., 742, the uppermost reservoir 733, up one, e.g., 743, of the 12 ramps leading from the reservoir immediately below, e.g., 742, the uppermost reservoir 733 at the back side of the diode pump (701 in FIG. 72), thereafter falling over the respective waterfall edge, e.g., 744, and down and into the uppermost reservoir 734 at the front side of the diode pump.

In response to a favorable tilt (e.g., 737 in FIG. 80) toward the back of the embodiment's diode pump, i.e., toward the turbine (726 in FIG. 80), water deposited into, and/or trapped within, reservoir 734, flows, e.g., 745, up one, e.g., 739, of the 12 ramps leading from the originating reservoir 734, thereafter falling over the respective waterfall edge, e.g., 746, and down and into the uppermost reservoir 733 at the back side of the diode pump. Water deposited into the uppermost reservoir 733 at the back side of the diode pump flows 735 over the backmost edge 747 of the uppermost reservoir 733 and thereover into the upper receiving chamber 712. Much of that water flows down one of the inclined floors 736L and 736R to the bottommost floor 748 of the upper receiving chamber 712 from which it flows into the lumen of the turbine tube 713 and therethrough through the water turbine 726 therein. The effluent flowing out of the water turbine flows into the lower receiving chamber 714 from which it flows into the lowermost reservoir (727 of FIG. 79) of the embodiment's diode pump (701 of FIG. 79).

FIG. 82 shows a perspective top-down view of the sectional view illustrated in FIG. 81.

FIG. 83 shows a perspective front side view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72-77 and 78-82. The tilted orientation of the embodiment is similar to the orientation of the embodiment 700R illustrated on the right side of FIG. 77.

FIG. 84 shows a perspective front side view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72-77 and 78-83. The tilted orientation of the embodiment is similar to the orientation of the embodiment 700L illustrated on the left side of FIG. 77.

FIG. 85 shows a perspective back side view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72-77 and 78-84. The tilted orientation of the embodiment is similar to the orientation of the embodiment 700R illustrated on the right side of FIG. 77.

FIG. 86 shows a perspective back side view of the same embodiment 700 of the present disclosure that is illustrated in FIGS. 72-77 and 78-85. The tilted orientation of the embodiment is similar to the orientation of the embodiment 700L illustrated on the left side of FIG. 77.

FIG. 87 shows a perspective side view of an embodiment 800 of the present disclosure. The illustrated embodiment is similar to an “autonomous underwater vehicle” (AUV) and is capable of cruising through a body of water below its surface. However, in FIG. 87 the embodiment is shown floating adjacent to an upper surface 801 of a body of water over which waves are passing. The embodiment incorporates, includes, and/or utilizes, four stabilizing and/or directional fins, e.g., 802, at a fore 803, forward, leading, and/or upper end, as well as four stabilizing and/or directional fins, e.g., 804, at an aft 805, stern, trailing, and/or lower end. In combination with a forward or backward thrust, the embodiment's fins, e.g., 802 and 804, enable and/or permit the embodiment to alter, adjust, control, regulate, change, and/or modify, its pitch, yaw, roll, course, direction, and/or movements.

The illustrated embodiment 800 has a hull, shape, form, and/or displacement, that is primarily cylindrical between its upper 803 and lower ends 805. The embodiment has an approximately torpedo-like shape. Mounted atop the upper end 803 is a radio transceiver 806, which in the embodiment illustrated in FIG. 87 is a phased-array antenna. Rotatably connected to its approximately frustoconical trailing end 805 is a propeller 807, the rotation of which tends to generate either a forward-pushing or backward-pulling thrust (depending on the direction in which the propeller is rotated).

The embodiment illustrated in FIG. 87 is floating, with an approximately vertical orientation, adjacent to an upper surface 801 of a body of water over which waves are passing and is thereby utilizing the rocking motions (e.g., surge) imparted to it by passing waves in order to energize a tilt-driven water ladder power take off (not visible) positioned within the cylindrical portion 800 of its hull.

FIG. 88 shows a side view of the same embodiment 800 of the present disclosure that is illustrated in FIG. 87. As the embodiment 800 floats adjacent to an upper surface 801 of a body of water over which waves pass, the relatively substantial surge motion 808 near the surface 801 is greater than the relatively diminished, smaller, and/or more feeble, surge motion 809 further and/or far beneath the surface 801. This differential surge motion imparted to the embodiment tends to cause the embodiment to rock 810 back-and-forth approximately laterally and approximately within the plane of the surge and/or within a plane approximately normal to the wave front.

FIG. 89 shows a side sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 87 and 88 wherein the vertical section plane is specified in FIG. 88 and the section is taken across line 89-89. The sectional view of FIG. 89 has left two components (power take off 818, propeller shaft 823, and propeller 807) unsectioned to facilitate explanation of the structure and operation of the embodiment.

At an upper end 803 of the embodiment 800 is a phased-array antenna 806 which receives encoded electromagnetic signals from one or more remote antennas (e.g., such as from ships, satellites, and shore-based facilities), and which transmits to one or more remote antennas (e.g., such as to ships, satellites, and shore-based facilities) at one or more particular and/or specific frequencies encoded electromagnetic signals. Signals received by the phased array antenna are decoded and/or otherwise processed by the embodiment's control system 811. Signals transmitted are encoded and/or otherwise prepared by the embodiment's control system 811.

The embodiment 800 includes a computational module 812 which incorporates, includes, and/or utilizes, a plurality of computational circuits including, but not limited to: computer processing units (CPUs), graphics processing units (GPUs), application-specific integrated circuits (ASICs), tensor processing units (TPUs), quantum processing units (QPUs), and optical processing units. The computational module also incorporates, includes, and/or utilizes, a plurality of memory circuits, a plurality of power management circuits, a plurality of network circuits, encryption/decryption circuits, etc., in addition to other circuits useful for the execution, completion, and/or implementation, of computational tasks, and for the gathering, sorting, compression, and/or storage, of computational results. The computational module includes electronic circuits, optical circuits, and other types of circuits. Heat generated by the activity, energization, and/or operation, of the electronic and/or optical circuits is transmitted, at least in part, conductively to the body of water 801 in which the embodiment floats and/or operates.

The embodiment 800 includes a pair of buoyancy control and trim adjustment modules 813 and 814 with which the embodiment's control system 812 may alter the overall density of the embodiment as well as the distribution of buoyancy within the embodiment.

The embodiment 800 incorporates, includes, and/or utilizes, fixed-wing fins, e.g., 815 and 816, which incorporate, include, and/or utilize, flaps, e.g., 817, to alter, adjust, control, regulate, change, and/or modify, its pitch, yaw, roll, course, direction, and/or movements, when the embodiment is being propelled forward or backward in response to thrust produced by the propeller 807.

A portion of the embodiment's interior is occupied by a power take off 818. The power take off progressively, incrementally, and/or serially, lifts water about and/or within a spiral hollow tube, and/or series of fluidly connected tubes, in response to tilting (810 in FIG. 88), tipping, rocking, and/or pivoting, of the embodiment within a vertical plane (e.g., normal to the resting surface 801 of the body of water in which the embodiment floats) passing through, and/or including, a central longitudinal axis of approximate radial symmetry of the embodiment. In response to such tilting, water within the spiral tube is moved from a relatively lower end of a tubular segment (i.e., an end relatively closer to the lower end 805 of the embodiment) to a relatively higher end of a tubular segment (i.e., an end relatively closer to the upper end 803 of the embodiment). With every tilt of sufficient angular deflection away from vertical (i.e., away from normal to the resting surface 801 of the water over which waves pass), water will tend to move from one relatively lower tubular segment to another relatively higher tubular segment.

When water has reached an upper end of the spiral tubular water channel 818, it passes into an upper reservoir chamber 819 proximate to that upper end. Water within the upper reservoir chamber flows downward under the influence of gravity and/or with respect to a head pressure. Water within the upper reservoir chamber flows into a turbine pipe (not visible) and therethrough flows into a lower reservoir chamber, the bottom of which is established by a lower reservoir pan 820, and the lateral walls of which are established by the spiral tubular water channel.

Water flowing downward through the turbine pipe (not visible) flows through, causes to rotate, and/or energizes, a water turbine (not visible) positioned therein. Rotations of the water turbine and its rigidly connected turbine shaft (not visible) impart rotational kinetic energy to an operably connected generator 821, thereby causing the generator to produce electrical power. At least a portion of the electrical power produced by the generator is stored within an energy storage module comprising a plurality of batteries (not visible).

When activated by the embodiment's control system 811 and energized by the embodiment's energy storage module (not visible), an electrical motor 822 causes the propeller 807 and its connected propeller shaft 823 to rotate. The embodiment's control system 811 is able to cause the motor to rotate the propeller 807 in a direction that causes the propeller to push the embodiment in a forward direction, i.e., toward its upper end 803, as well as in a direction that causes the propeller to pull the embodiment in a backward direction, i.e., away from its upper end 803.

FIG. 90 shows a side view of the power take off (PTO) of the same embodiment of the present disclosure that is illustrated in FIGS. 87-89.

An outer spiral tubular water channel 818 is comprised of fluidly-connected tubular segments through which water flows in a counter-clockwise direction (when viewed from above the upper end of the PTO proximal to the PTO's upper reservoir chamber 819). The outer spiral tubular water channel 818 surrounds an inner spiral tubular water channel (not visible) in which water flows in a clockwise direction (when viewed from above the upper end of the PTO proximal to the PTO's upper reservoir chamber 819).

In response to wave-induced tilting of the PTO relative to a nominally vertical longitudinal axis of approximate radial symmetry water in the outer spiral tubular water channel 818 moves incrementally through, around, and upward, within that channel in a counter-clockwise direction. In response to the same wave-induced tilting of the PTO relative to a nominally vertical longitudinal axis of approximate radial symmetry water in the inner spiral tubular water channel (not visible) moves incrementally through, around, and upward, within that channel in a clockwise direction.

Water trapped within the lower reservoir chamber (not visible) defined in part by the lower reservoir pan 820 enters a lowermost portion of each of the inner and outer spiral tubular water channels. Water enters each of the inner and outer spiral tubular water channels through a respective aperture in a respective channel-specific lowermost tubular segment. After passing through the respective lowermost tubular segment of each of the inner and outer spiral tubular water channels, water remains trapped within each of the inner and outer spiral tubular water channels as wave-induced tilting of the PTO incrementally causes that water to flow through, around, and upward, within each respective channel.

At the summit of each spiral flow of water, within each respective inner and outer spiral tubular water channel, the water within each channel is deposited within and/or into the upper reservoir chamber 819 through a channel-specific aperture in the uppermost tubular segment of each of the inner and outer spiral tubular water channels. Thus, water from the lower reservoir chamber enters each of the inner and outer spiral tubular water channels through a respective aperture at the base of each channel, and winds it way in respective clockwise and counter-clockwise directions through those respective spiral tubular water channels, after which the water from each channel is deposited into the upper reservoir chamber 819. Water within the upper reservoir chamber then flows, under gravitationally-induced head pressure, through a turbine pipe (not visible), and a water turbine (not visible) therein, which imparts rotational kinetic energy to a generator 821 operably-connected to the generator, thereby causing the generator to produce electrical power.

The PTO is a closed system. In other words, the water flowing upward within the inner and outer spiral tubular water channels, the water within the upper and lower reservoir chambers, and the water that flows through the turbine pipe to the water turbine, is the same water flowing cyclically through the PTO, over and over again. Because the PTO is a closed system, the gas within the PTO is trapped therein and neither flows out of the PTO, flows into the PTO, nor is exchanged with gases outside the PTO.

FIG. 91 shows a top-down sectional view of the power take off (PTO) of the same embodiment of the present disclosure that is illustrated in FIGS. 87-89, and/or of the same PTO illustrated in FIG. 90, wherein the horizontal section plane is specified in FIG. 90 and the section is taken across line 91-91.

In response to wave-induced tilting and/or rocking of the embodiment, when it floats in an approximately vertical orientation adjacent to an upper surface of a body of water over which waves pass, water flows in a counter-clockwise direction (when viewed from above its uppermost end as in the illustration of FIG. 91) through the outer spiral tubular water channel 818. After flowing up through most of the outer spiral tubular water channel, water flows 824 into and through the uppermost portion of the outer spiral tubular water channel. That water continues to flow from tubular segment to tubular segment, flowing 825 and 826 around the uppermost portion of the channel. Finally, the water flows 827 into the final, uppermost tubular segment 829, and that flow 828 becomes exposed beneath the section plane. Water that reaches the final, uppermost tubular segment then flows 830 out through outer spiral tubular water channel effluent pipe 831 and is deposited within the upper reservoir chamber 819.

Arrows shown in gray indicate flows of water within a portion of the respective spiral tubular water channel that is enclosed and/or below the section plane. Arrows shown in black indicated flows of water within a portion of the respective spiral tubular water channel that is exposed due to the section plane passing below its upper channel wall.

Similarly, in response to the same wave-induced tilting and/or rocking of the embodiment, when it floats in an approximately vertical orientation adjacent to an upper surface of a body of water over which waves pass, water flows in a clockwise direction (when viewed from above its uppermost end as in the illustration of FIG. 91) through the inner spiral tubular water channel 832. After flowing up through most of the inner spiral tubular water channel, water flows 833 into and through the uppermost portion of the inner spiral tubular water channel. That water continues to flow from tubular segment to tubular segment, flowing 834 and 835 around the uppermost portion of the channel. Finally, the water flows 836 into the final, uppermost tubular segment 837, and that flow 838 becomes exposed beneath the section plane. Water that reaches the final, uppermost tubular segment then flows 839 out through inner spiral tubular water channel effluent pipe 840 and is deposited within the upper reservoir chamber 819.

When the embodiment, and the illustrated embodiment PTO, floats in an approximately vertical orientation adjacent to an upper surface of a body of water over which waves pass, water within the upper reservoir chamber 819 is elevated relative to the lower reservoir chamber (not visible) and as such is imbued with a gravitationally-induced head pressure that tends to cause it to flow into turbine pipe 841, which is fluidly-connected to the turbine pipe. As water flows down, toward the lower reservoir chamber (not visible), it flows through, engages, energizes, and causes to rotate, a water turbine 842 positioned therein. Rotations of the water turbine impart rotational kinetic energy to a generator (821 in FIG. 90) through a turbine shaft (not visible), thereby causing the generator to produce electrical power.

FIG. 92 shows a closeup perspective view of the same top-down sectional view of the power take off (PTO) illustrated in FIG. 90, which is a view of the PTO of the same embodiment of the present disclosure that is illustrated in FIGS. 87-89. The vertical section plane of FIGS. 91 and 92 is specified in FIG. 90 and the section is taken across line 91-91.

As water moves upward and through the outer spiral tubular water channel 818 it reaches, and/or flows 828 into, the final tubular segment 829 of that water channel, after which it flows 830 through outer spiral tubular water channel effluent pipe 831 into the upper reservoir chamber 819. Similarly, as water moves upward and through the inner spiral tubular water channel 832 it reaches, and/or flows 838 into, the final tubular segment 837 of that water channel, after which it flows 839 through inner spiral tubular water channel effluent pipe 840 into the upper reservoir chamber 819.

Water within the upper reservoir chamber 819 flows 843, under the influence of gravity, into the turbine pipe 841, and therethrough flows through the water turbine (not visible) imparting to it energy.

FIG. 93 shows a side sectional view of the power take off (PTO) of the same embodiment of the present disclosure that is illustrated in FIGS. 87-89, and/or of the same PTO illustrated in FIGS. 90-92, wherein the vertical section plane is specified in FIG. 91 and the section is taken across line 93-93.

Water 844 trapped in the PTO's lower reservoir chamber, comprised of lateral walls formed by the inside surface of the inner and/or centermost surface and/or wall of the inner spiral tubular water channel 832, and the bottom wall formed by the lower reservoir pan 820, is drawn into the lowermost portions of the inner 832 and outer 818 spiral tubular water channels. Water 844 from the lower reservoir chamber flows 845 into the lowermost tubular segment 846 of the outer spiral tubular water channel 818 through an aperture (not visible) within that lowermost tubular segment. Water 844 from the lower reservoir chamber flows 847 into the lowermost tubular segment 848 of the inner spiral tubular water channel 832 through an aperture (not visible) within that lowermost tubular segment.

In response to wave-induced rocking of the embodiment, and of the PTO therein, relative to a nominally vertical longitudinal axis of approximate radial symmetry water in both the inner 832 and outer 818 spiral tubular water channels moves incrementally through, around, and upward, within each channel, eventually reaching the uppermost tubular segment of each spiral tubular water channel and thereafter flowing into the upper reservoir chamber 819 and increasing the mass and/or volume of water 849 therein. Water flows 830 and 839 into the upper reservoir chamber from the respective effluent pipes 831 and 840 of the respective inner and outer spiral tubular water channels.

Water 849 within the upper reservoir chamber 819 flows 843 into the turbine pipe 841, after which it flows 850 down through that pipe until it flows 851 into and through the water turbine 842, thereby transmitting rotational kinetic energy to its respective turbine shaft 852, which, in turn, transmits that energy to the operably-connected generator 821, thereby causing the generator to produce electrical power. A portion, if not all, of the electrical power produced by the generator 821 is transmitted to the energy storage module 853 and/or to the batteries, e.g., 854, therein.

Water flowing 855 out of the water turbine, and/or the turbine pipe 841, enters the pool of water collected within the lower reservoir chamber 844, and thereafter is drawn into one of the inner 832 or outer 818 spiral tubular water channels . . . to repeat the cycle of wave-induced flow and energy production.

FIG. 94 shows an abstracted, stylized, and/or schematized, version of the side sectional view of the power take off (PTO) that is illustrated in FIG. 93. The purpose of FIG. 94 is to better illustrate the cyclic process of using wave-induced motions of the PTO to lift water from a lower reservoir chamber 844 up to an upper reservoir chamber 819 from where its gravitational potential energy and head pressure are used to rotate a water turbine 842 and energize an operably-connected generator 821 so as to produce electrical power from the energy imparted to the PTO by the passing waves.

Water 844 within a lower reservoir chamber is drawn 856 into the lowermost ends of a pair of counter-rotating spiral tubular water channels, with the pair of channels representing in FIG. 94 as a dashed outline 859 of a cylindrical cross-section. Wave motion causes the water within the spiral tubular water channels to flow 857 upward through those water channels. And, at the uppermost ends of the counter-rotating spiral tubular water channels, the water flows 858 out of the water channels and into an upper reservoir chamber 819 where it is added to water 849 already entrained therein.

Water 849 within the upper reservoir chamber 819 flows 843 into and down 850 through the turbine pipe 841, eventually flowing 851 into the water turbine 842 positioned within the turbine pipe and causing that water turbine to rotate. Rotations of the water turbine are transmitted by a turbine shaft (852 in FIG. 93) to an operably-connected generator 821 thereby causing the generator to produce electrical power. After being discharged by the water turbine, the effluent water flows 855 back into the lower reservoir chamber, rejoining the body of water 844 from which it was originally drawn into the spiral tubular water channels.

FIG. 95 shows a closeup perspective sectional view of a lowermost portion and/or end of the power take off (PTO) illustrated in FIGS. 90-94, and of the embodiment illustrated in FIGS. 87-89. The illustration in FIG. 95 has a portion of the lower reservoir pan 820 cut away in order to permit the display and/or inspection of the spiral tubular water channels otherwise obscured by that pan.

Water collected within the lower reservoir chamber (844 in FIG. 93) enters the outer spiral tubular water channel 818 through an aperture 860 in the lowermost tubular segment 861 of that water channel. Water collected within the lower reservoir chamber (844 in FIG. 93) enters the inner spiral tubular water channel 832 through an aperture 862 in the lowermost tubular segment 863 of that water channel.

FIG. 96 shows a closeup perspective sectional view of a typical tubular segment of which the inner (832 in FIGS. 91-93) and outer (818 in FIGS. 91-93) spiral tubular water channels of the power take off (PTO) illustrated in FIGS. 90-94, the PTO of the embodiment illustrated in FIGS. 87-89, is in part comprised. The inner wall (i.e., the vertical wall closest to the radial center about which the tubular segment bends) of the illustrated tubular segment 864 has been removed to permit examination and/or illustration of the interior of the channel 865 therein.

The illustrated tubular segment is a nominal tubular segment. The lowermost and uppermost tubular segments of each of the inner and outer spiral tubular water channels are different from the tubular segments between those lowermost and uppermost tubular segments, as they are from the medial tubular segment 864 illustrated in FIG. 96.

The tubular segment 864 defines a channel 865 that follows an upward spiraling path about a vertical longitudinal axis of rotation. The collection, set, and/or group, of interconnected tubular segments of which each spiraling tubular water channel is comprised approximately define the surface a cylinder. A reference line 866 is included in FIG. 96 to help illustrate the upward slope and curvature of the illustrated tubular segment.

When water flows through one of the embodiment's spiral tubular water channels, it tends to flow through each of the tubular segments of which that spiral tubular water channel is comprised as it incrementally flows through the upward spiraling water channel. When water flows through a tubular segment, water flows 867 into, and/or enters, the tubular segment through a medial aperture 868 in an upper wall of the tubular segment. Water flowing and/or entrained within the interior channel 865 of the tubular segment can flow 869 backward (i.e., in a direction of flow opposite that of the flow through the respective spiral tubular water channel) and/or accumulate at the back end (i.e., the rightmost end with respect to the orientation of the tubular segment illustrated in FIG. 96) of the tubular segment.

However, when the tilt angle of the PTO, and/or the embodiment in which the PTO is incorporated, is advantageous, e.g., resulting in a change in the orientation of the tubular segment 864 in which the back end becomes elevated to a relatively greater height than the nominally higher forward end, then water within the interior channel 865 of the tubular segment tends to flow 870 toward the forward end (i.e., “forward” with respect to the nominal direction of water flow through the spiral tubular water channel) of the tubular segment. If the water within the tubular segment flows far enough, then it reaches a forward aperture 871 and flows down and out of that aperture, nominally into and through the medial aperture 868 of the next tubular segment in the spiral tubular water channel, and/or of which the spiral tubular water channel is comprised. Similarly, it is water that has flowed to and out of the forward aperture 871 of the prior tubular segment in the spiral tubular water channel that flows 867 into the illustrated tubular segment.

The illustrated tubular segment 864 tends to keep water trapped within that tubular segment when the orientation, tilt, rocking, and/or angular offset from vertical, of the PTO and/or the respective embodiment are unfavorable. This prevents water within a spiral tubular water channel from flowing backward within the spiral tubular water channel when the orientation, tilt, rocking, and/or angular offset from vertical, of the PTO and/or the respective embodiment is not favorable. However, when the orientation, tilt, rocking, and/or angular offset from vertical, of the PTO and/or the respective embodiment becomes favorable, then the water within each tubular segment tends to flow 870 forward, thereby increasing its distance above the lower reservoir chamber and the water turbine.

Each wave-powered lifting of water within each of the embodiment's two spiral tubular water channels tends to increase the gravitational potential energy of the water within the spiral tubular water channel, and because the back flowing of that water is inhibited if not prevented, the potential energy imparted to the water is captured.

FIG. 97 shows a closeup perspective sectional view of two typical tubular segments of which the inner (832 in FIGS. 91-93) and outer (818 in FIGS. 91-93) spiral tubular water channels of the power take off (PTO) illustrated in FIGS. 90-94, the PTO of the embodiment illustrated in FIGS. 87-89, are in part comprised. The inner wall (i.e., the vertical wall closest to the radial center about which the tubular segments bend) of the illustrated tubular segments 864 and 873 have been removed to permit examination and/or illustration of the interiors of the channels 865 and 874 therein. The illustration in FIG. 97 adds a precursor tubular segment 873 to the tubular segment 864 illustrated in FIG. 96.

A reference plane 866 is included in FIG. 97 to help illustrate the upward slope and curvature of the illustrated pair of fluidly-connected tubular segments 873 and 864.

Water flows 875 in to the hollow interior 874 of tubular segment 873 through that tubular segment's medial aperture 876. In response to favorable tilting of the array of tubular segments, i.e., of the respective spiral tubular water channel of the respective PTO, water within the interior water channel 874 of tubular segment 873 flows 877 forward within the tubular segment, reaching and flowing 867 down through that tubular segment's forward aperture, which is also the medial aperture 868 of tubular segment 864. Thus, the water within tubular segment 873 flows 867 into tubular segment 864, and, in response to favorable tilting of the array of tubular segments, flows 870 forward to that tubular segment's forward aperture 871, and then flows 872 down and through that forward aperture, nominally into the interior of the next tubular segment within the fluidly connected series, and/or chain, of such tubular segments of which the respective spiral tubular water channel is comprised.

FIG. 98 shows a close up perspective view of two typical tubular segments of which the inner (832 in FIGS. 91-93) and outer (818 in FIGS. 91-93) spiral tubular water channels of the power take off (PTO) illustrated in FIGS. 90-94, the PTO of the embodiment illustrated in FIGS. 87-89, are in part comprised. However, in the illustration of FIG. 98, the lowermost tubular segment 878 is the first, initial, starting, and/or lowermost, tubular segment of its respective spiral tubular water channel.

Tubular segment 878 is the tubular segment through which water from the lower reservoir chamber enters the spiral tubular water channel in order to begin its ascension up the spiral water channel to the upper reservoir chamber (819 in FIG. 93). Water flows 879 into the hollow interior of tubular segment 878 through aperture 880. Thereafter it flows forward and flows into the next, following, subsequent, and/or downstream, tubular segment 881 through the forward aperture (not visible) positioned within the lower wall of tubular segment 878 at its forward end 882 which is coincident, and/or shared, with the medial aperture (not visible) of tubular segment 881. That water then flows forward within tubular segment 881 until it reaches and flows 883 down and through that tubular segment's forward aperture 884, nominally thereby entering, and/or flowing into, the next, following, subsequent, and/or downstream, tubular segment.

A reference plane 866 has been included in FIG. 98 to help illustrate the upward slope and curvature of the illustrated pair of fluidly-connected tubular segments 878 and 881.

FIG. 99 shows a closeup perspective sectional view of two typical tubular segments of which the inner (832 in FIGS. 91-93) and outer (818 in FIGS. 91-93) spiral tubular water channels of the power take off (PTO) illustrated in FIGS. 90-94, the PTO of the embodiment illustrated in FIGS. 87-89, are in part comprised. However, in the illustration of FIG. 99, the uppermost tubular segment 885 is the last, final, ending, and/or uppermost, tubular segment of its respective spiral tubular water channel.

Tubular segment 885 is the tubular segment through which water pumped upward through wave action at the spiral tubular water channel flows out of the spiral tubular water channel and flows into its respective upper reservoir chamber (819 in FIGS. 91-93) prior to its descent down the respective turbine pipe (819 in FIG. 93). Water flows 886 out of the hollow interior of tubular segment 885 through respective spiral tubular water channel effluent pipe 887. Note that this final and/or uppermost tubular segment 885 lacks a forward aperture (that would typically be positioned at 888).

In the illustration of FIG. 99, water flows from a prior (not shown) tubular segment 889 into, down, and through, the medial aperture 890 of the penultimate tubular segment 891 of the respective (not shown) spiral tubular water channel. Then, when the orientation of the respective PTO is favorable, the water within the interior of tubular segment 891 flows forward and then flows into, down, and through, the forward aperture of tubular segment 891, thereby concomitantly flowing into, down, and through, the medial aperture of tubular segment 885 and entering the interior water channel of tubular segment 885. Then, when the orientation of the respective PTO is favorable, the water within the interior of tubular segment 885 flows forward and then flows 886 laterally out of spiral tubular water channel effluent pipe 887, thereby being deposited within the upper reservoir chamber (819 in FIG. 93).

A reference plane 866 has been included in FIG. 99 to help illustrate the upward slope and curvature of the illustrated pair of fluidly-connected tubular segments 891 and 885.

FIG. 100 shows a closeup perspective sectional view of two typical tubular segments of which the inner (832 in FIGS. 91-93) and outer (818 in FIGS. 91-93) spiral tubular water channels of the power take off (PTO) illustrated in FIGS. 90-94, the PTO of the embodiment illustrated in FIGS. 87-89, are in part comprised. The inner wall (i.e., the vertical wall closest to the radial center and/or longitudinal axis 894 about which the tubular segments bend) of the illustrated tubular segments 892 and 893 have been removed to permit examination and/or illustration of the hollow interiors of those tubular segments.

A reference plane 866 is included in FIG. 100 to help illustrate the upward slope and curvature of the illustrated pair of fluidly-connected tubular segments 892 and 893.

The orientation of the two fluidly-connected tubular segments 892 and 893 illustrated in FIG. 100 is such that the longitudinal axis about they spiral is vertical as it would be when the PTO, and the respective embodiment, in which it is incorporated is resting in nominally vertical direction (as illustrated in FIG. 88) adjacent to the surface of a resting (i.e., wave-free) body of water. The alignment of the longitudinal axis of rotation of the tubular segments 892 and 893 with the gravitational force acting on those segments and the water within them is further illustrated in FIG. 100 by the surface 895 of the water 896 trapped and/or entrained within tubular segment 892, and by the surface 897 of the water 897 trapped and/or entrained within tubular segment 893. The surfaces 895 and 897 of both respective entrained bodies of water 896 and 898 are parallel with the reference plane 866 which is oriented within FIG. 100 to be horizontal and nominally parallel to the resting surface of the body of water at which the respective PTO and embodiment float.

In this non-tilted orientation, the water 896 and 898 within each tubular segment is sequestered, trapped, and/or entrained, at the back and/or lowermost end of the respective water channel within each tubular segment. That water is unable to flow back down the respective spiral tubular water channel of which the illustrated tubular segments are a part.

FIG. 101 shows a close up perspective sectional view of the same two tubular segments illustrated in FIG. 100. In FIG. 101 the orientation of the tubular segments, and/or the longitudinal axis about which they spiral, has been altered to illustrate the effect of tilting of the respective PTO and/or embodiment in an unfavorable direction.

And, as with the FIG. 100, the inner wall (i.e., the vertical wall closest to the radial center and/or longitudinal axis 894 about which the tubular segments bend) of the illustrated tubular segments 892 and 893 have been removed to permit examination and/or illustration of the hollow interiors of those tubular segments.

Unlike in the illustration of FIG. 100, where the longitudinal axis about which the fluidly-connected tubular segments spiraled was vertical and normal to the resting surface of a body of water on which the respective embodiment would float when oriented as illustrated in FIG. 88, the longitudinal axis about which the fluidly-connected tubular segments illustrated in FIG. 101 spiral is tilted, as if, and/or as it would be, if the respective PTO and embodiment of which they are a part is moved out of a purely vertical orientation by a passing wave, and into an unfavorable orientation, tilt, and/or angular offset. With respect to the orientation of the tubular segments illustrated in FIG. 101, the tilting would not be regarded as favorable since the water 896 and 898 within each of the respective fluidly-connected tubular segments is not induced to flow in a forward direction, i.e., toward their respective forward apertures, but is instead induced to flow 901 and 902, respectively, backward and be trapped and/or entrained at a back end of each tubular segment's respective hollow interior.

The illustration in FIG. 101 includes the reference plane 866 also included within the illustration of FIG. 100. However, that reference plane, as well as the longitudinal axis about which the tubular segments 892 and 893 spiral, have been tilted by an angle 899 with respect to the illustration, and/or illustrated orientation, of the tubular segments in FIG. 101. The nominal un-tilted and/or horizontal reference plane of FIG. 100 is included in FIG. 101 as plane 900.

In the unfavorably-tilted orientation of the tubular segments 892 and 893 illustrated in FIG. 101, the water 896 and 898 within each of those tubular segments is sequestered, trapped, and/or entrained, at the back and/or lowermost end of each of the respective interior water channels within each of those tubular segments. That water is unable to flow back down the respective spiral tubular water channel of which the illustrated tubular segments are a part.

The unfavorable tilting of the tubular segments 892 and 893 has resulted in a reduction in the area of each respective upper and/or free surface 895 and 897 of each respective body of water 896 and 898 entrained within each respective tubular segment (i.e., in comparison to the area of each respective upper and/or free surface 895 and 897 of each respective body of water 896 and 898 entrained within each respective tubular segment of the un-tilted orientation illustrated in FIG. 100.

FIG. 102 shows a closeup perspective sectional view of the same two tubular segments illustrated in FIGS. 100 and 101. In FIG. 102 the orientation of the tubular segments, and/or the orientation of the longitudinal axis about which they spiral, has been altered to illustrate the effect of tilting the respective PTO and/or embodiment in a favorable direction, i.e., a direction, orientation, and/or angular offset which promotes a forward flow of fluid within the hollow interiors of the tubular segments, e.g., in contrast to the unfavorable direction of tilt illustrated in FIG. 101.

And, as with the FIGS. 100 and 101, the inner wall (i.e., the vertical wall closest to the radial center and/or longitudinal axis 894 about which the tubular segments bend) of the illustrated tubular segments 892 and 893 have been removed to permit examination and/or illustration of the hollow interiors of those tubular segments.

The illustration in FIG. 102 includes the reference plane 866 also included within the illustrations of FIGS. 100 and 101. However, with respect to the orientation of the tubular segments illustrated in FIG. 102, the original, un-tilted reference plane (as illustrated in FIG. 100), as well as the longitudinal axis about which the tubular segments 892 and 893 spiral, have been tilted by an angle 906 with respect to the illustration, and/or illustrated orientation, of the tubular segments in FIG. 102. The nominal un-tilted and/or horizontal reference plane of FIG. 100 is included in FIG. 101 as plane 900.

Unlike in the illustration of FIG. 100, where the longitudinal axis about which the fluidly-connected tubular segments spiraled was vertical and normal to the resting surface of a body of water on which the respective embodiment would float when the embodiment is oriented as illustrated in FIG. 88, and unlike the illustration of FIG. 101, where the longitudinal axis about which the fluidly-connected tubular segments spiraled was tilted in an unfavorable direction, the longitudinal axis about which the fluidly-connected tubular segments illustrated in FIG. 102 spiral is tilted, as if, and/or as it would be, if the respective PTO and embodiment of which they are a part is moved out of a purely vertical orientation by a passing wave, and is in a favorable orientation, tilt, and/or angular offset. With respect to the orientation of the tubular segments illustrated in FIG. 102, the tilting is favorable since the water 896 and 898 within each of the respective fluidly-connected tubular segments 892 and 893 is induced and/or made to flow 902 and 903 in a forward direction, i.e., toward their respective forward apertures. In fact, because of their forward flows 902 and 903, the water 896 and 897, respectively, within each respective tubular segment 892 and 893 is flowing up to, down and through its respective forward aperture.

The water 896 within the hollow interior of tubular segment 892 is flowing 904 through, into, and/or out of, the forward aperture 905 of tubular segment 892, which is fluidly connected, and/or adjacent to the medial aperture of tubular segment 893. After flowing 904 from tubular segment 892 into tubular segment 893, the water originating from the interior of tubular segment 892 mixes with the water already flowing 903 forward within the interior of tubular segment 893. The mixed water 898 flows 903 forward toward the forward aperture 907, and subsequently flows down, through, and past, forward aperture 907, nominally into a succeeding tubular segment (not shown)

FIG. 103 shows a tubular power take off (PTO) similar, analogous, and/or equivalent, to the PTO illustrated in FIGS. 89-102. This embodiment of the present disclosure illustrates some important characteristics of the embodiments of the present disclosure.

The embodiment of the power take off illustrated in FIG. 103 is simplified to facilitate explanation. However, it should be understood that longer, e.g., a much greater number of turns in the spiral water channel, and more complex embodiments are included within the scope of the present invention.

The embodiment illustrated in FIG. 103 is a single, continuous fluid channel through which a fluid (e.g., water) advances about a path of ever-increasing elevation, and/or distance from the origin of the fluid being advanced. The fluid flow occurs in response to favorable tilting, rocking, and/or angular deflections, that move the longitudinal, nominally vertical, axis about which the fluid flows and approximately parallel to the escalating vertical displacements of the fluid. Furthermore, in response to tilts of unfavorable direction and/or angle, the fluid remains trapped within the fluid channel at a height approximately equal to its greatest vertical displacement—the fluid does not flow backward and/or down the fluid channel toward to aperture through which it entered the fluid channel.

Please note that directions of fluid flow within the tubular channel of the illustrated PTO are indicated by arrows outside those tubular channels. The reader should interpret the arrows signified as indicators of fluid flow as indicating fluid flow within the adjacent part or portion of the tubular PTO.

With respect to the simplified PTO illustrated in FIG. 103, fluid flows 908, and/or enters the initial tubular segment 909 of the fluid channel through an aperture 910 at an end of the initial tubular segment 909. In response to favorable tilting of the PTO, water flows 911 forward through the spiral tubular segment 909. Water flowing 911 to the forward end of the tubular segment 909 falls and/or flows 912 through the approximately vertical connecting tube segment 913 thereby flowing into and/or entering the next tubular segment 914 in the tubular PTO.

In response to favorable tilting of the PTO, water within tubular segment 914 flows 915 forward through that spiral tubular segment. Water flowing 915 to the forward end of the tubular segment 914 falls and/or flows 916 through the approximately vertical connecting tube segment 917 thereby flowing into and/or entering the next tubular segment 918 in the tubular PTO.

In response to favorable tilting of the PTO, water within tubular segment 918 flows 919 forward through that spiral tubular segment. Water flowing 918 to the forward end of the tubular segment 919 falls and/or flows 920 through the approximately vertical connecting tube segment 921 thereby flowing into and/or entering the next tubular segment 922 in the tubular PTO.

In response to favorable tilting of the PTO, water within tubular segment 922 flows 923 forward through that spiral tubular segment. Water flowing 922 to the forward end of the tubular segment 923 falls and/or flows 924 through the approximately vertical connecting tube segment 925 thereby flowing into and/or entering the next tubular segment 926 in the tubular PTO.

In response to favorable tilting of the PTO, water within tubular segment 926 flows 927 forward through that spiral tubular segment. Water flowing 927 to the forward end of the tubular segment 926 falls and/or flows 928 through the approximately vertical connecting tube segment 929 thereby flowing into and/or entering the next tubular segment 930 in the tubular PTO.

In response to favorable tilting of the PTO, water within tubular segment 930 flows 931 forward through that spiral tubular segment. Water flowing 930 to the forward end of the tubular segment 931 flows 932 into the approximately vertical connecting tube segment 933 thereby flowing 935 out of an aperture 936 positioned at a nominally uppermost end of the last tubular segment 930 in the illustrated PTO.

In response to unfavorable tilting, water within any of the tubular segments, other than the initial tubular segment 909, will flow, e.g., 937, backward and become entrained and/or trapped in the closed, aperture-free backmost, and/or nominally lowermost, portion, e.g., 938, of each respective tubular segment.

The water exiting and/or flowing 935 out of the nominally uppermost end of the illustrated PTO is elevated with respect to the aperture 910 through which it entered the PTO. The illustrated PTO, and especially more extensive, longer, and/or PTOs with greater numbers of spiral windings, are capable of elevating fluids to significant heights when driven by waves of sufficient energy, period, and surge length. And the gravitational potential energy imparted to fluids so elevated may then be passed through a water- or fluid-turbine in order to energize an operably-connected generator, thereby producing electrical power. The resulting gravitational potential energy of the elevated water can be used for other purposes in which the head pressure of the water is utilized directly, or for other useful purposes still.

An embodiment of the present disclosure does not include, incorporate, and/or utilize, a generator. An embodiment of the present disclosure does not include, incorporate, and/or utilize, a water turbine. An embodiment of the present disclosure does not include, incorporate, and/or utilize, a turbine shaft, e.g., an embodiment utilizes a hubless water turbine which is itself a generator.

FIG. 104 shows a perspective side view of an embodiment 1000 of the present disclosure. The illustrated embodiment is similar to an “autonomous underwater vehicle” (AUV) and is capable of cruising through a body of water below its surface. However, in FIG. 104 the embodiment is shown floating adjacent to an upper surface 1001 of a body of water over which waves are passing. With respect to the orientation of the embodiment illustrated in FIG. 104, the “forward end” is at the top of the page (e.g., above the surface 1001 of the water), and the “back end” 1002 is at the bottom of the page, and the embodiment's propeller 1003 extends from the back end. The sides of the illustrated embodiment are referred to as “broad sides”, e.g., 1004, and “narrow sides”, e.g., 1005.

When cruising below the surface 1001 of a body of water, the embodiment's propeller 1003 typically pushes the embodiment toward its forward end. However, when the embodiment's propeller is rotated in an opposite direction, the propeller pulls the embodiment backward.

The embodiment incorporates, includes, and/or utilizes, two stabilizing and/or directional fins, e.g., 1006, along each of its narrow sides, as well as one stabilizing and/or directional fin, e.g., 1007, on each of its broad sides, positioned adjacent to the back end 1002 of the embodiment.

At least in part because of its oblong shape with respect to horizontal cross-sections when floating adjacent to a surface 1001 of a body of water over which waves are passing, the embodiment will tend to orient itself, and/or be driven to an orientation, in which its broad sides are approximately parallel to the wave front 1008, and/or normal to the direction of wave propagation 1009. The embodiment illustrated in FIG. 104 is oriented such that its broad sides are aligned with a wave trough 1010. Because of its tendency to adopt, and/or be driven to, this wave-front-aligned orientation, the embodiment tends to be rocked 1011 by waves within a plane of motion that is parallel to the direction of wave propagation 1009.

Mounted to the top of the embodiment is a phased array radio antenna 1012.

FIG. 105 shows a perspective top-down view of the same embodiment 1000 of the present disclosure that is illustrated in FIG. 104. In FIG. 104 the embodiment is shown cruising through a body of water below its surface 1001, as the result of thrust produced by its motor-driven propeller, where that motor is powered, at least in part, by electrical power generated by the embodiment's power take off (PTO) as it floated adjacent to the water's surface 1001 at some earlier time.

The embodiment's control system (not visible) steers the embodiment as it cruises through the articulation of flaps, e.g., 1013, incorporated within each of the four fins 1006 and 1014-1016 mounted and/or attached to its two narrow sides, e.g., 1005 (with two fins on each narrow side), and through the articulation of flaps incorporated within each fin 1017 and 1007 (see FIG. 104) mounted and/or attached to its two broad sides 1004 and 1018 (see FIG. 104). In the illustration of FIG. 105, the embodiment's propeller 1003 is pushing the embodiment in a forward direction, i.e., toward the forward end 1019 of the embodiment. However, the embodiment's control system can also use the flaps on the embodiment's six fins to steer the embodiment when the control system rotates the propeller 1003 in an opposite direction, thereby pulling the embodiment backward in a direction in which the forward end 1019 becomes the trailing end.

FIG. 106 shows a side view of the same embodiment 1000 of the present disclosure that is illustrated in FIGS. 104 and 105.

Propeller 1003 is operably-connected to propeller shaft 1020.

FIG. 107 shows a side view of the same embodiment 1000 of the present disclosure that is illustrated in FIGS. 104-106.

FIG. 108 shows a top-down view of the same embodiment 1000 of the present disclosure that is illustrated in FIGS. 104-107.

FIG. 109 shows a bottom-up view of the same embodiment 1000 of the present disclosure that is illustrated in FIGS. 104-108.

FIG. 110 shows a side sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 104-109 wherein the vertical section plane is specified in FIG. 108 and the section is taken across line 110-110.

Propeller 1003, and the turbine shaft 1020 operably-connected to the propeller, are rotated by motor 1021 in either of two directions. The first direction of rotation generates thrust that pushes and/or propels the embodiment in a forward direction (i.e., toward the top of the page with respect to the embodiment orientation illustrated in FIG. 110). The second direction of rotation generates thrust that pulls and/or propels the embodiment in a backward direction (i.e., toward the bottom of the page with respect to the embodiment orientation illustrated in FIG. 110). Motor 1021 is energized, at least in part, by electrical energy produced by the embodiment's power take off (PTO) 1022-1024 which is identical to the PTO illustrated and described in FIGS. 72-86. A portion of the electrical energy that is produced by the embodiment's PTO is stored within an energy storage and computing module 1027. And, a portion of the electrical energy that energizes motor 1021 is energy derived from, obtained from, and/or transmitted to the motor by, the embodiment's energy storage and computing module.

As illustrated and explained in relation to FIGS. 72-86, the PTO is comprised of adjacent columns of ramps and reservoirs (as illustrated in FIGS. 78-80) which raise water (i.e., toward generator 1024) in response to wave action at the embodiment when the embodiment is floating in an approximately vertical orientation adjacent to the surface of a body of water over which waves pass (as illustrated in FIG. 104). Turbine shaft 1023 (711 in FIGS. 79 and 80) operably connects generator 1024 (702 in FIGS. 79 and 80) to a water turbine (not visible in FIG. 110, see 726 in FIGS. 79 and 80).

PTO 1022-1024 is positioned within a compartment and/or space 1025 within the embodiment's interior. Much of the embodiment's interior 1026 is comprised of a buoyant material, which includes, but is not limited to, structural polyurethane foam.

The embodiment incorporates, includes, and/or utilizes, forward and back buoyancy and trim modules 1028 and 1029, respectively, with, and/or through, which the embodiment's control system 1030 controls the orientation of the embodiment, especially when it cruises beneath the surface of the body of water in which it floats (as illustrated in FIG. 105). A surplus of buoyancy, which the control system manifests through control of the forward and back buoyancy and trim modules helps position the embodiment while it floats in an approximately vertical orientation adjacent to the surface 1001 of a body of water in order to utilize the ambient wave action at the surface to energize its PTO by incrementally and/or successively driving water up the ramps (as illustrated in FIGS. 78-80).

Because the embodiment tends to adopt, and/or be driven to, an azimuthal and/or lateral-angular orientation that aligns its broad sides with the prevailing and/or dominant wave front, and/or aligns its broad sides such that they approximately normal to the prevailing and/or dominant direction of wave propagation. Therefore, the rocking imparted to, and/or induced in, the embodiment in response to wave action tends to be aligned so as to lift water at the greatest possible rate within the PTO, and/or to impart a maximal amount of wave energy to the embodiment's PTO.

Through its phased-array antenna 1012, the embodiment's control system 1030 receives encoded transmissions and/or signals of electromagnetic, radio, and/or optical, energy from remote sources and/or antennas. The control system decrypts, and/or interprets, those encoded signals and processes them. When appropriate, the control system transmits the data and/or computational tasks within an encoded signal to a network, collection, set, and/or plurality, of computing devices positioned and operating within the embodiment's energy storage and computing module 1027. At least a portion, and typically all, of the computing devices and other electronic, optical, networking, memory, and other devices within the energy storage and computing module are energized by energy transmitted to them by the energy storage and computing module.

At least one computer within the energy storage and computing module 1027 may transmit to the control system 1030 at least a portion of computational results obtained from, and/or generated by, the execution of a computational task transmitted to one or more computers within the energy storage and computing module by the control system. The control system encrypts, formats, and/or encodes, data and/or computational results obtained from the computers in the energy storage and computing module, as well as data and/or computational results that it produces, and then transmits encoded transmissions and/or signals of electromagnetic, radio, and/or optical, energy to remote receivers and/or antennas.

The circuits and/or components within the embodiment's energy storage and computing module 1027 includes, but is not limited to: a plurality of computational circuits including, but not limited to: computer processing units (CPUs), graphics processing units (GPUs), application-specific integrated circuits (ASICs), tensor processing units (TPUs), quantum processing units (QPUs), and optical processing units. The energy storage and computing module also incorporates, includes, and/or utilizes, a plurality of memory circuits, a plurality of power management circuits, a plurality of network circuits, encryption/decryption circuits, etc., in addition to other circuits useful for the execution, completion, and/or implementation, of computational tasks, and for the gathering, sorting, compression, and/or storage, of computational results. The energy storage and computing module includes electronic circuits, optical circuits, and other types of circuits.

Heat generated by the activity, energization, and/or operation, of the electronic and/or optical circuits is transmitted, at least in part, conductively to the body of water 1001 in which the embodiment floats and/or operates.

The energy storage and computing module 1027 includes, but is not limited to: batteries, capacitors, electrolyzers, hydrogen storage components, fuel cells.

FIG. 111 shows a perspective view of the vertical sectional view illustrated in FIG. 110.

FIG. 112 shows a perspective side view of an embodiment 1100 of the present disclosure. The illustrated embodiment is a power take off (PTO) that elevates a fluid in response to rocking, and/or tilting, within a plane approximately parallel to the plane and/or wall about which stacks and/or arrays of ramps of opposing and/or complementary angles are separated. The illustrated PTO elevates its internal fluid in response to rocking within a plane parallel to a broad surface of a wall about which the embodiment's fluid flows, first flowing parallel and adjacent to a first side of the wall, then flowing around a vertical edge of the wall from the first side to a second side, then flowing parallel and adjacent to the second side of the wall, then flowing around a vertical edge of the wall from the first side to the second side, and then repeating such a pattern of flow until the fluid is discharged from the fluid-elevating ramps.

After being discharged from the fluid-elevating ramps, the fluid elevated by the embodiment in response to rocking, e.g., in response to wave action at a vessel to which the PTO is affixed or mounted, is directed into a high-energy fluid reservoir (not visible) and from there into an upper end of a turbine tube 1101 in which a hubless fluid turbine 1102 is positioned and rotated by the descending fluid within the turbine tube. The effluent from that fluid turbine is then collected within a low-energy fluid reservoir (not visible).

Fluid from the low-energy reservoir (not visible) is drawn into the lowest fluid-elevating ramp within the embodiment and is thereafter incrementally raised to ever increasing elevations within the embodiment until it is again discharged, and until it again imparts to the fluid turbine a portion of the gravitational potential energy imparted to it by the embodiment in response to rocking of the embodiment, e.g., in response to wave action.

FIG. 113 shows a side view of the same embodiment 1100 of the present disclosure that is illustrated in FIG. 112.

FIG. 114 shows a front side view of the same embodiment 1100 of the present disclosure that is illustrated in FIGS. 112 and 113.

FIG. 115 shows a top-down view of the same embodiment 1100 of the present disclosure that is illustrated in FIGS. 112-114.

FIG. 116 shows a side sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 112-115 wherein the vertical section plane is specified in FIG. 115 and the section is taken across line 116-116.

The illustrated section discloses an approximately vertical first array of inclined ramps and/or flumes, e.g., 1103, of a first angularity, angle, and/or slope, up and over which a fluid, e.g., water, inside the embodiment is able to flow, e.g., 1104 from a respective basin, e.g., 1124. When the fluid flows, e.g., 1105, far enough along a flume, e.g., 1103, the fluid will tend to fall over a raised distal ramp edge and/or precipice, e.g., 1106, and become deposited, entrained, trapped, and/or captured, within a basin, spillway, and/or trough, e.g., 1107, positioned beneath each respective precipice and formed, instantiated, fabricated, and/or manifested, at least in part, by a floor, e.g., 1128. The fluid deposited into a spillway, e.g., 1107, is then able to flow up and over a complementary flume of a second angularity, angle, and/or slope, where the second slope is on opposite sign as the first slope with respect to a planar projection of the complementary ramps onto a Cartesian plot, i.e., if the ramps of the vertical array are ascending with respect to leftward flows (e.g. with respect to the orientation of the illustration in FIG. 116), then the respective complementary flumes will be ascending with respect to rightward flows (perhaps by the same or similar angle with respect to a longitudinal axis of the turbine pipe 1101, and perhaps by a different angle).

When fluid flowing 1127 from the uppermost basin 1126 on and/or over flume 1130 flows 1108 to and over the uppermost raised distal ramp edge and/or precipice 1109 is deposited, entrained, trapped, and/or captured, within the embodiment's high-energy fluid reservoir 1110, thereby tending to alter the height and/or level of that reservoir's surface 1111. A bottom wall of the high-energy fluid reservoir is comprised, at least in part, of a wall 1129. Fluid within the high-energy fluid reservoir is driven by gravity to flow 1112 downward within the interior channel 1113 of the turbine pipe 1101. Eventually, the fluid flows 1114 into and through hubless fluid turbine 1115 thereby imparting rotational energy to the generator 1116 of the fluid turbine assembly 1102, causing the generator to produce electrical power.

Effluent fluid flowing 1117 out of the hubless fluid turbine 1115 is deposited into the embodiment's low-energy fluid reservoir 1118 thereby tending to alter the height and/or level of that reservoir's surface 1119. The embodiment's low-energy fluid reservoir 1118 is held, entrained, trapped, and/or captured, within a basin 1120, comprised at least in part by a bottom wall 1131, from which fluid is again drawn into the embodiment's PTO by flowing up and over a lowermost inclined ramp of a second approximately vertical array of inclined ramps (not visible in the section due to the placement of the section plane).

Please note that the fluid flows specified in FIG. 116 do not occur unless the embodiment is to a sufficient degree and/or angle tilted (to the left, and/or in a counterclockwise direction, with respect to the embodiment orientation illustrated in FIG. 116, i.e., with the lower-right corner of the illustrated embodiment raised to an elevation and/or height sufficiently greater than the elevation and/or height of the lower-left corner). The flows indicated and discussed with respect to FIG. 116 are illustrative of the actual flows that would occur in response to a favorable tilting of the embodiment. The fluid in the high-energy and low-energy fluid reservoirs show horizontal and/or flat, resting and/or un-tilted surfaces. However, in the event of tilting, the surfaces of those reservoirs would altered to remain normal to the force of gravity and/or tangentially parallel to an average surface of the Earth.

FIG. 117 shows a side sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 112-116 wherein the vertical section plane is specified in FIG. 115 and the section is taken across line 117-117. Please note that the sectional illustration of FIG. 117 reveals a portion of what was revealed by the sectional illustration of FIG. 116.

The sectional illustration of FIG. 117 includes virtually the entire interior of the embodiment (i.e., simply removing by section the foremost lateral wall) whereas the sectional illustration of FIG. 116 included only the backmost portion of the embodiment's interior. The sectional illustration of FIG. 116 removed by section the second array of inclined ramps and/or flumes, and a medial wall and/or barrier that separates the adjacent first and second arrays of inclined ramps. Thus the medial wall separating the first and second arrays of flumes may be seen in the sectional illustration of FIG. 117, as well as the second array of flumes in the foreground of that medial wall. A portion of the first array of flumes (revealed without obstruction in the sectional illustration of FIG. 116) may be seen behind the medial wall in the sectional illustration of FIG. 117.

In response to a favorable tilt of the embodiment 1100, fluid 1118 pooled within the embodiment's low-energy fluid reservoir 1118 flows 1134 up, and along, flume 1131 there after flowing 1135 over the precipice at the end of that flume, thereby falling into basin 1124. Fluid pooled, deposited, collected, and/or standing, in basin 1124, will, in response to a favorable tilt, then flow (1104 in FIG. 116) up flume 1103, positioned on the far side (with respect to the embodiment orientation illustrated in FIG. 117) of the medial wall 1136, with relative left 1137 and right 1138 edges, and flow 1105 into basin 1107. Fluid pooled, deposited, collected, and/or standing, in basin 1107, will, in response to a favorable tilt, then flow up a complementary flume 1139 and flow 1140 into basin 1125.

This process of fluid in the embodiment flowing up and over the precipice of one flume, and subsequently being depositing into a respective basin adjacent to a first vertical edge and/or side of the medial wall separating complementary flumes and/or arrays of flumes, and thereafter flowing up and over the precipice of a complementary (e.g., a flume of an opposite slope) flume, and subsequently being depositing into a respective basin adjacent to a second and/or opposite vertical edge and/or side of the medial wall, continues until the fluid is lifted, elevated, and/or flows into the embodiment's high-energy fluid reservoir 1110.

Fluid pooled, deposited, collected, and/or standing, in basin 1141, will, in response to a favorable tilt, flow (1142 in FIG. 116) up a flume 1133 and flow over that flume's precipice and be deposited into basin 1123. Fluid pooled, deposited, collected, and/or standing, in basin 1123, will, in response to a favorable tilt, flow 1143 up a complementary flume 1132 and flow 1144 over that flume's precipice 1145 and be deposited into basin 1126. Fluid pooled, deposited, collected, and/or standing, in basin 1126, will, in response to a favorable tilt, flow (1127 in FIG. 116) up a complementary flume 1130 and flow 1108 over that flume's precipice 1109 and be deposited into the embodiment's high-energy fluid reservoir 1110.

Fluid pooled, deposited, collected, and/or standing, in the embodiment's high-energy fluid reservoir 1110 flows, in response to the pull of gravity, into and through turbine pipe 1101 wherein it flows through, energizes, and causes to rotate a hubless fluid turbine (1115 in FIG. 116) thereby imparting rotational kinetic energy to the hubless fluid turbine's operably-connected generator (1116 in FIG. 116), thereby causing the generator to produce electrical power. The fluid effluent flowing 1117 out of the turbine pipe 1101 is deposited into the embodiment's low-energy fluid reservoir, and will, in response to a favorable tilt of the embodiment, flow up flume 1131 and into basin 1124, and begin the tilt-energized electrical power production cycle again.

Please note that the fluid flows specified in FIG. 117 do not occur unless the embodiment is to a sufficient degree and/or angle tilted (to the right, and/or in a clockwise direction, with respect to the embodiment orientation illustrated in FIG. 117, i.e., with the lower-left corner of the illustrated embodiment raised to an elevation and/or height sufficiently greater than the elevation and/or height of the lower-right corner). The flows indicated and discussed with respect to FIG. 117 are illustrative of the actual flows that would occur in response to a favorable tilting of the embodiment. The fluid in the high-energy and low-energy fluid reservoirs show horizontal and/or flat, resting and/or un-tilted surfaces. However, in the event of tilting, the surfaces of those reservoirs would altered to remain normal to the force of gravity and/or tangentially parallel to an average surface of the Earth.

The cyclic clockwise and counterclockwise tilting of the embodiment illustrated in FIGS. 112-117, when that tilting is of sufficient degree, angularity, and/or extent, and of sufficient duration, and/or period, will cause fluid to incrementally flow from basin to basin within the embodiment until that fluid is deposited within the high-energy fluid reservoir and imparts a portion of its energy, stored within the fluid as gravitational potential energy, to the fluid turbine within the turbine pipe, thereby enabling the generator operably-connected to the fluid turbine to produce electrical power.

FIG. 118 shows a top-down sectional view of the same embodiment of the present disclosure that is illustrated in FIGS. 112-117 wherein the slanted, but approximately horizontal, section plane is specified in FIGS. 116 and 117 and the section is taken across line 118-118.

Chamber 1120 entrains, holds, stores, and/or encloses, the embodiment's low-energy fluid reservoir (1118 in FIGS. 116 and 117). The adjacent flume arrays are encased within four lateral outer walls 1156. The first array of flumes (e.g., 1103, 1130, 1133, and 1148 in FIG. 116) is separated from the second array of flumes (e.g., 1131, 1132, 1139, 1151, and 1152 in FIG. 117) by medial wall 1136, which is characterized by left 1137 and right 1138 vertical edges.

Fluid flowing 1154 up flume 1152 flows 1155 over precipice 1157 and is deposited into basin 1146. Fluid then flows 1158 laterally within basin 1146 from the side of that basin below (with respect to the illustration in FIG. 118) the medial wall 1136, and adjacent to medial wall edge 1138, to the side of that basin above the medial wall, after which it flows 1147 up flume 1148 until it flows 1149 over precipice 1159 and is deposited into basin 1150. Fluid then flows 1160 laterally within basin 1150 from the side of that basin above (with respect to the illustration in FIG. 118) the medial wall 1136, and adjacent to medial wall edge 1137, to the side of that basin below the medial wall, after which it flows 1153 up flume 1151 passing above the section plane and out of the illustration's field of view.

The embodiment illustrated in FIGS. 112-118 is an example and is not a limitation on the scope of the present invention. The angles of the flumes are arbitrary and embodiments with flumes of any angle, and any variety of angles, are included in the scope of the present invention.

The embodiment illustrated in FIGS. 112-118 may be mounted to a buoy, ship, vessel, autonomous surface vessel (ASV), autonomous underwater vehicle (AUV), unmanned underwater vehicle (UUV), and to any other vessel, vehicle, floating object, or anchored, tethered, or moored object. All combinations of the embodiment illustrated in FIGS. 112-118 are included within the scope of the present invention.

The embodiment illustrated in FIGS. 112-118 comprises only a single first, and a single second, array of flumes. However, other embodiments included within the scope of the present invention incorporate, include, and/or utilize, two or more complementary pairs of first and second flume arrays. All such embodiments are included within the scope of the present invention.

The embodiment illustrated in FIGS. 112-118 comprises a particular number of flumes per flume array. However, other embodiments included within the scope of the present invention incorporate, include, and/or utilize, one, two, three, and any number of flumes per flume array. All such embodiments are included within the scope of the present invention.

An embodiment similar to the one illustrated in FIGS. 112-118 utilizes water as its fluid, and air as the gas through which the water flows. However, other embodiments included within the scope of the present invention incorporate, include, and/or utilize, other types, kinds, and/or mixtures of fluids, both liquid and gaseous. All such embodiments are included within the scope of the present invention.

The embodiment illustrated in FIGS. 112-118 comprises flumes of particular widths and lengths. However, other embodiments included within the scope of the present invention incorporate, include, and/or utilize, flumes of different widths and/or different lengths. All such embodiments are included within the scope of the present invention.

The embodiment illustrated in FIGS. 112-118 incorporates, includes, and/or utilizes, a hubless fluid turbine and an operably-connected generator. However, other embodiments included within the scope of the present invention incorporate, include, and/or utilize, other types of fluid turbines and/or other types of generators. Some embodiments do not utilize a turbine and instead utilize the circulated fluid (e.g., stirring) and/or the fluids gravitational potential energy for another useful purpose. Some embodiments do not utilize an electrical generator and instead utilize the head pressure of their respective elevated fluids to create some other type of energy (e.g., compressed air, compressed hydraulic fluid) or to perform some type of useful work (e.g., raising a fluid out of a body of freshwater buffeted by waves to an elevated location on an adjacent shoreline).

The embodiment illustrated in FIGS. 112-118 is designed to be mounted to, and/or used in conjunction with, a wave-buffeted platform floating on a body of water. However, other embodiments included within the scope of the present invention are mounted to, and/or combined with, or used in conjunction with, other devices characterized by, and/or capable of imparting to an embodiment, the rocking and/or tilting motion required for it to operate. All such embodiments are included within the scope of the present invention.

The embodiment illustrated in FIGS. 112-118 may be combined with the seafloor-mounted, near-shore wave-driven apparatus illustrated in FIGS. 72-86. In fact, the embodiment of the present disclosure disclosed in FIGS. 112-118 is similar to the power take off (PTO) incorporated, included, and/or utilized, within the embodiment illustrated in FIGS. 72-86. A difference between the two PTOs is that the PTO of the embodiment illustrated in FIGS. 72-86 uses inclined ramps to deposit fluid into a basin that is characterized by a horizontal bottom and uses precipices that have a vertical wall beneath each precipice (e.g., similar to a “cliff”). Whereas the PTO of FIGS. 112-118 uses inclined ramps to deposit fluid into a basin that is an extension of the inclined ramp arising and/or ascending from it, and uses precipices that are extensions of the end of each inclined ramp so that the void beneath each precipice provides each respective basin with additional volume in which to entrain and/or hold fluid.

Embodiments of the present disclosure similar to the one illustrated in FIGS. 87-89 incorporate, include, and/or utilize, power take offs of the kinds illustrated in FIGS. 12-14, 25-37, 41-54, and 63-67. The scope of the present invention includes embodiments which incorporate, include, and/or utilize, other versions, alternatives, variations, modifications, and/or alterations of the wave- and/or tilt-induced water-lifting power take offs illustrated and explained herein as examples of the present disclosure.

Such embodiments may use the pressurized air to drive an air turbine, or to perform some other useful work.

Embodiments of the present disclosure operate a variety of internal pressures. An embodiment utilizes favorable tilting to elevate fluids within a highly pressurized interior. Another embodiment utilizes favorable tilting to elevate fluids within an interior at low pressure, or near vacuum.

Many varieties of embodiments have been disclosed as examples and illustrations of the present disclosure, and some of those embodiments incorporate features, components, elements, designs, and/or attributes, that are illustrated only for a single or very few of the embodiments.
